Why I cannot turn on the power supply smoothly when the loads are motors, light bulbs or capacitive loads?

Why I cannot turn on the power supply smoothly when the loads are motors, light bulbs or capacitive loads?

If you connect the power supply to motors, light bulbs, or high capacitive loads, you will have a high output surge current when you turn on the power supply and this high surge current will cause failure of startup. We suggest using power supply with constant current limiting protection to deal with these loads.
