A Surge Protection Device is optimized for a single voltage. Therefore, SPD should be chosen according to the actual operating voltage of the part that need to be protected.Secondly, the voltage protection level shows what is the maximum voltage appeared at output side when a specified surge is coming to the SPD. In general, the lower the voltage protection level, and the higher the discharge or surge current from SPD, means the better protection that the SPD provides.

Enclosed power supplies:

• 35-125W applications: The RD, RT and RQ series provide dual, triple, and quadruple output.
• 150-320W applications: The QP series comes with 4 different outputs.
• 190-240W applications: The semi-potted HDP series provides dual output.

PCB-type power supplies:

• 25-250W applications: The PD and PT series provide dual and triple output.
• 45-200W medical applications: The MPD, MPT and MPQ series offer dual, triple, and quadruple output.

Configurable power supplies:

• 400W fanless, the UMP-400 series is a convection cooled 1U height modular power supply and can provide up to 4 different outputs.
• 450-1000W for ITE applications, MP series provides up to 7 different isolated outputs.
• 650-1200W for ITE and medical applications, NMP series can provide up to 6 different isolated outputs with the NMS single output modules from 3~55VDC. With the NMD dual output module more outputs are possible in the 3~30VDC range. Additionally, the NMP offers a 5V AUX output.

Please also see our “NMP Page”

Desktop-type power supplies:

• 25-50W applications, our GP series is a triple-output type industrial adaptor. 

DC-DC modules:

• 1-2W applications, the SMD-type DETN series comes with +/-5, 12 or 15V symmetrical outputs.
• 3-30W applications, the DIP-type DCW, DCWN, RDDW, DKM, DKMW, DKA30 series come with +/- 5, 12 or 15V symmetrical outputs.
• 20W ultra-wide input range requirements, the DIP-type RDDW20UW series can provide a +/-12, 15 and 24V symmetrical output.
• 15W applications, the DIP-type DKE15 series offers a +/-5, 12, 15 or 24V symmetrical output.
• 30W applications, the DIP-type TKA30 series offers a 5V output in addition to a +/-12 or 15V symmetrical output.
• 10-15W applications, the on-board-type NSD series can provide a +/- 5, 12 or 15V symmetrical output.

The number of outputs, the available output voltage range and minimum load requirements are some key aspects to be considered when it comes to choosing a multiple output type PSU.

Basic power supplies in this category have a so-called minimum load requirement. These types of PSU rely on one same internal transformer to provide different outputs. For all outputs to work properly, a minimum current should always be drawn from the main output channel.

See below example how this is shown in the specification for the RPT-60A

More advanced power supplies such as the RT-65A do not have this restriction:

There are two options to select a multiple output PSU: a standard PSU with fixed output voltages, or modular power supplies. Modular PSUs can be personalized according to one’s systems requirements and offer much more flexibility than fixed output voltages PSUs. For instance, our NMP modular medical power supply series come with up to 6 slots for different output voltages from 3 to 55V which can be connected in series and parallel to adapt to each application.

This information can be found back in our installation manual, please visit “Installation Manual-MEAN WELL Switching Power Supply Manufacturer” and select the right product (group) and language.

Yes, CSP-3000 and PHP-3500-HV series both come with an inclusive choice of output voltages (120, 250, 400VDC). Also, our IP67 rated HEP-1000 series can provide DC output up to 100VDC.

All MEAN WELL power supplies come with at least one fuse on the line path¹. The internal fuse is designed to handle the nominal current on the whole range of input voltages; for the same power, at low input voltages, the current drawn by the PSU will be higher:

If you want a more adapted protection for a specific input voltage, you could add an external fuse to protect the power supply. Considering that it will only protect the PSU (no other appliances connected after it), you should refer to the datasheet of the power supply and look for the typical input current under your input voltage. The fuse should be rated slightly higher than this current value. The selected external fuse should be a Slow-Blow type, this to avoid it is triggered by the inrush current of the power supply. For reference, most of MEAN WELL power supplies use type-T slow acting fuses. 

Further please take into consideration that fuses characteristics are given for an operating temperature of 25^oC. Exceeding this value will lower the current rating and shorten its lifetime. Similarly, when operated in cold areas, the current rating will be increased.

Owing to line (voltage)-drop, we suggest the extension made from AC cable. In case DC cable extension is necessary, please consider Line-Drop leading to insufficient Vf so that the LED model or lamp may fail to switch ON. Moreover, EMC performance and characteristic may also be affected by DC cable extension.

First, you have to know your Led lamp specification in order to screen out a suitable Led driver range (Wattage, Voltage, Max Current CC or CV). From those ranges, further check a compatible dimming function. Hereunder is a table to show you the pros and cons of Dimming Function you can find in MW’s catalogue.

MEAN WELL has several charger products, and we suggest choosing them first. Chargers would be more suitable since they are designed for charging applications. Safety and approvals should be taken into account based on the final application. If you are unable to find a proper model in our charger series, our LED CC models can be used as charger. Please choose suitable products after confirming the current and voltage specification on the datasheet of the battery.

3 in 1 dimming circuit would drain 0.1mA per model. Dividing the rated current of the dimmer by the 0.1mA, and we could know how many units can be controlled by one dimming device. For resistance dimming applications, resistance for 100% dimming output would be 100K ohm divided number of models.

A LED strip is normally a Constant Voltage application (CV). For this type of CV application MEAN WELL has design the PWM, IDLV and ODLV series which will allow CV applications to dim.

3 in 1 dimming is the most common application used in LED dimming with the feature that it does not have to work with any specific dimmer. The only thing that has to be verified is that whether the dimmer (1~10V/10V PWM/resistance) is compatible with the definition advised in our specs.

All MEAN WELL chargers are preset for lead-acid batteries. For other products that can customize the charging curve (such as ENC / NPB series), customers can customize their charging curve depending on the charging and discharging characteristics of batteries. If you have other requirements, please use the contact us function on this website.

Noise is directly related to the fan which is built into the power supply. Lowering the airflow of the fan means reducing the heat dissipation ability. It will also influence the reliability of the products. Furthermore, minimum airflow of fans is defined by Safety Organization and a safety appendage will be needed if using a new fan. If fan noise is a critical concern, we suggest to select FANLESS products or contact MEAN WELL for other possibilities according to the conditions of use.

There are two different applications when power supplies are connected in series. One is to generate plus minus voltage, another is to increase total output voltage. Connection methods are as follows:

(1) Connection for plus and minus voltage are shown as follow

(2) To increase the total output voltage (Output current remain the same). Diodes connect in parallel at output side of the driver is necessary to prevent damage during start up. The voltage rating of diode shall greater than V1 + V2(shown as figure below), in addition, peak forward surge current rating shall greater than rated current.

* Because part of the signal ground is shorted with output ground, strongly suggest to use isolated signals to achieve control scheme, in order to prevent damage to the product.

MEAN WELL has launched ENC, HEP-600C, GC, PA, PB, RPB and RCB series for battery charge applications (30~1000W). However, if these models cannot fulfill your requirements, there is an alternative solution. Power supplies with constant current limiting as overload protection are suggested. Charge current varies in battery percentage (full or flat), there is high possibility to trigger overload protection when battery is low, those with overload protection as hiccup or shutdown will stop charging the battery in low battery condition. Yet, using a power supply as charging purpose is considered as overload usage, modification is required. Please Contact Us for the request.

An adaptor may need connection of a power cord to receive energy needed from the utility. You can refer to the specification of the adaptor for the connector (AC inlet) at the adaptor end of the power cord; Different countries/regions vary in type of AC socket and voltage, please look at the table below for the information of the AC plug you need.

MEAN WELL’s LED product specification normally exhibits V-I characteristics. Per the characteristics, there are generally two types of drivers, the “CC” type and the “CC+CV” type. “CC” type of driver is suitable only for LED applications whereas “CC+CV” is for either LED applications or general switching power supply applications. The section that is not suitable for LED applications are represented by dotted line, and based on the protection procedures it can be categorized into hiccup mode and constant current mode; in this section, the tolerance of current is not defined but only the characteristic of current is displayed. If customers attempt not to see a very high current under short circuit conditions, those models with hiccup mode for this section can be selected; if there are applications with motors or capacitive load, those with constant current can be chosen.

There are 2 types of Power Factor Correction circuits; one is Single Stage; the other is Two Stage.

Single Stage power supply combines functions of power factor correction and converter in one circuit but Two Stage use two separate circuits. Compared to Single Stage, Two Stage design is more complex and costly, but the immunity performance of Two Stage power supply against AC mains is much better than that of Single Stage power supply. In addition, Two Stage power supplies manifest better ripple noises performance on output. Owing to that Single Stage is only suitable for fields with quality AC mains but Two Stage can be used in serious circumstances for LED drivers or as industrial switching power supplies.

It is the small unwanted residual periodic variation of the direct current (DC) output of a power supply which has been derived from an alternating current (AC) source. The wave form is shown as figure below.

There are two AC contents, also known as Ripple and Noise (R&N), on the DC output. The first one, coming from sine wave rectification, is at a low frequency which is 2 times of the input frequency; the second one is at high frequency which is from the switching frequency. For measuring high frequency noise, a configuration of an oscilloscope with a bandwidth of 20MHz, a scope probe with shortest ground wire possible, and add 0.1uF and 47uF capacitors in parallel with test point for filtering out noise interference are required.

1. To increase the reliability of the power supply, we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a power supply with 130W of output power or more. By doing this, you can effectively boost the reliability of the power supply in your system.

2. We also need to consider about ambient temperature of the power supply and whether there is additional device for dissipating the heat. If the power supply is working in a high temperature environment, we need to make some derating to the output power. The derating curve of “ambient temperature” versus “output power” can be found on our specifications.

3. Choosing functions based on your application:

• Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Overload Protection (OLP), and etc.
• Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc.
• Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function.

4. Make sure that the model qualifies for the safety standards and EMC regulations you need.

All MEAN WELL power supplies have an internal fuse except for the DDRH series.

2. We also need to consider about ambient temperature of the power supply and whether there is additional device for dissipating the heat. If the power supply is working in a high temperature environment, we need to make some derating to the output power. The derating curve of “ambient temperature” versus “output power” can be found on our specifications.

3. Choosing functions based on your application:

• Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Overload Protection (OLP), and etc.
• Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc.
• Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function.

4. Make sure that the model qualifies for the safety standards and EMC regulations you need.

All MEAN WELL power supplies have an internal fuse except for the DDRH series.

A Surge Protection Device is optimized for a single voltage. Therefore, SPD should be chosen according to the actual operating voltage of the part that need to be protected.Secondly, the voltage protection level shows what is the maximum voltage appeared at output side when a specified surge is coming to the SPD. In general, the lower the voltage protection level, and the higher the discharge or surge current from SPD, means the better protection that the SPD provides.

• 10-15W applications, the on-board-type NSD series can provide a +/- 5, 12 or 15V symmetrical output.

The number of outputs, the available output voltage range and minimum load requirements are some key aspects to be considered when it comes to choosing a multiple output type PSU.

Basic power supplies in this category have a so-called minimum load requirement. These types of PSU rely on one same internal transformer to provide different outputs. For all outputs to work properly, a minimum current should always be drawn from the main output channel.

See below example how this is shown in the specification for the RPT-60A

More advanced power supplies such as the RT-65A do not have this restriction:

There are two options to select a multiple output PSU: a standard PSU with fixed output voltages, or modular power supplies. Modular PSUs can be personalized according to one’s systems requirements and offer much more flexibility than fixed output voltages PSUs. For instance, our NMP modular medical power supply series come with up to 6 slots for different output voltages from 3 to 55V which can be connected in series and parallel to adapt to each application.

This information can be found back in our installation manual, please visit “Installation Manual-MEAN WELL Switching Power Supply Manufacturer” and select the right product (group) and language.

Yes, CSP-3000 and PHP-3500-HV series both come with an inclusive choice of output voltages (120, 250, 400VDC). Also, our IP67 rated HEP-1000 series can provide DC output up to 100VDC.

All MEAN WELL power supplies come with at least one fuse on the line path¹. The internal fuse is designed to handle the nominal current on the whole range of input voltages; for the same power, at low input voltages, the current drawn by the PSU will be higher:

If you want a more adapted protection for a specific input voltage, you could add an external fuse to protect the power supply. Considering that it will only protect the PSU (no other appliances connected after it), you should refer to the datasheet of the power supply and look for the typical input current under your input voltage. The fuse should be rated slightly higher than this current value. The selected external fuse should be a Slow-Blow type, this to avoid it is triggered by the inrush current of the power supply. For reference, most of MEAN WELL power supplies use type-T slow acting fuses. 

Further please take into consideration that fuses characteristics are given for an operating temperature of 25^oC. Exceeding this value will lower the current rating and shorten its lifetime. Similarly, when operated in cold areas, the current rating will be increased.

Owing to line (voltage)-drop, we suggest the extension made from AC cable. In case DC cable extension is necessary, please consider Line-Drop leading to insufficient Vf so that the LED model or lamp may fail to switch ON. Moreover, EMC performance and characteristic may also be affected by DC cable extension.

First, you have to know your Led lamp specification in order to screen out a suitable Led driver range (Wattage, Voltage, Max Current CC or CV). From those ranges, further check a compatible dimming function. Hereunder is a table to show you the pros and cons of Dimming Function you can find in MW’s catalogue.

MEAN WELL has several charger products, and we suggest choosing them first. Chargers would be more suitable since they are designed for charging applications. Safety and approvals should be taken into account based on the final application. If you are unable to find a proper model in our charger series, our LED CC models can be used as charger. Please choose suitable products after confirming the current and voltage specification on the datasheet of the battery.

3 in 1 dimming circuit would drain 0.1mA per model. Dividing the rated current of the dimmer by the 0.1mA, and we could know how many units can be controlled by one dimming device. For resistance dimming applications, resistance for 100% dimming output would be 100K ohm divided number of models.

A LED strip is normally a Constant Voltage application (CV). For this type of CV application MEAN WELL has design the PWM, IDLV and ODLV series which will allow CV applications to dim.

3 in 1 dimming is the most common application used in LED dimming with the feature that it does not have to work with any specific dimmer. The only thing that has to be verified is that whether the dimmer (1~10V/10V PWM/resistance) is compatible with the definition advised in our specs.

All MEAN WELL chargers are preset for lead-acid batteries. For other products that can customize the charging curve (such as ENC / NPB series), customers can customize their charging curve depending on the charging and discharging characteristics of batteries. If you have other requirements, please use the contact us function on this website.

Noise is directly related to the fan which is built into the power supply. Lowering the airflow of the fan means reducing the heat dissipation ability. It will also influence the reliability of the products. Furthermore, minimum airflow of fans is defined by Safety Organization and a safety appendage will be needed if using a new fan. If fan noise is a critical concern, we suggest to select FANLESS products or contact MEAN WELL for other possibilities according to the conditions of use.

There are two different applications when power supplies are connected in series. One is to generate plus minus voltage, another is to increase total output voltage. Connection methods are as follows:

(1) Connection for plus and minus voltage are shown as follow

(2) To increase the total output voltage (Output current remain the same). Diodes connect in parallel at output side of the driver is necessary to prevent damage during start up. The voltage rating of diode shall greater than V1 + V2(shown as figure below), in addition, peak forward surge current rating shall greater than rated current.

* Because part of the signal ground is shorted with output ground, strongly suggest to use isolated signals to achieve control scheme, in order to prevent damage to the product.

MEAN WELL has launched ENC, HEP-600C, GC, PA, PB, RPB and RCB series for battery charge applications (30~1000W). However, if these models cannot fulfill your requirements, there is an alternative solution. Power supplies with constant current limiting as overload protection are suggested. Charge current varies in battery percentage (full or flat), there is high possibility to trigger overload protection when battery is low, those with overload protection as hiccup or shutdown will stop charging the battery in low battery condition. Yet, using a power supply as charging purpose is considered as overload usage, modification is required. Please Contact Us for the request.

An adaptor may need connection of a power cord to receive energy needed from the utility. You can refer to the specification of the adaptor for the connector (AC inlet) at the adaptor end of the power cord; Different countries/regions vary in type of AC socket and voltage, please look at the table below for the information of the AC plug you need.

MEAN WELL’s LED product specification normally exhibits V-I characteristics. Per the characteristics, there are generally two types of drivers, the “CC” type and the “CC+CV” type. “CC” type of driver is suitable only for LED applications whereas “CC+CV” is for either LED applications or general switching power supply applications. The section that is not suitable for LED applications are represented by dotted line, and based on the protection procedures it can be categorized into hiccup mode and constant current mode; in this section, the tolerance of current is not defined but only the characteristic of current is displayed. If customers attempt not to see a very high current under short circuit conditions, those models with hiccup mode for this section can be selected; if there are applications with motors or capacitive load, those with constant current can be chosen.

There are 2 types of Power Factor Correction circuits; one is Single Stage; the other is Two Stage.

Single Stage power supply combines functions of power factor correction and converter in one circuit but Two Stage use two separate circuits. Compared to Single Stage, Two Stage design is more complex and costly, but the immunity performance of Two Stage power supply against AC mains is much better than that of Single Stage power supply. In addition, Two Stage power supplies manifest better ripple noises performance on output. Owing to that Single Stage is only suitable for fields with quality AC mains but Two Stage can be used in serious circumstances for LED drivers or as industrial switching power supplies.

It is the small unwanted residual periodic variation of the direct current (DC) output of a power supply which has been derived from an alternating current (AC) source. The wave form is shown as figure below.

There are two AC contents, also known as Ripple and Noise (R&N), on the DC output. The first one, coming from sine wave rectification, is at a low frequency which is 2 times of the input frequency; the second one is at high frequency which is from the switching frequency. For measuring high frequency noise, a configuration of an oscilloscope with a bandwidth of 20MHz, a scope probe with shortest ground wire possible, and add 0.1uF and 47uF capacitors in parallel with test point for filtering out noise interference are required.

1. To increase the reliability of the power supply, we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a power supply with 130W of output power or more. By doing this, you can effectively boost the reliability of the power supply in your system.

2. We also need to consider about ambient temperature of the power supply and whether there is additional device for dissipating the heat. If the power supply is working in a high temperature environment, we need to make some derating to the output power. The derating curve of “ambient temperature” versus “output power” can be found on our specifications.

3. Choosing functions based on your application:

• Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Overload Protection (OLP), and etc.
• Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc.
• Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function.

4. Make sure that the model qualifies for the safety standards and EMC regulations you need.

All MEAN WELL power supplies have an internal fuse except for the DDRH series.
