There are some minimum-load requirements on MEAN WELL’s multi-output power supplies. Please read the specification first before connecting to the load.

Please refer to “Current range” in the specification as shown in the table below: Channel 1 requires a 2A minimum-load; channel 2 requires 0.5A; Channel 3 requires 0.1A ; Channel 4 does not need any minimum-load.
