What is Inrush Current

Inrush Current refers to the peak current of power equipment at the moment of power on. This "Inrush Current" will appear every time you turn on the power and then the current will come back to normal. Although it will not damage the power supply, we suggest not turning the power supply ON/OFF very quickly within a short time. Besides, if there are several power supplies turning on at the same time, the dispatching system of AC source may shut off and go into protection mode because of the huge inrush current. It is suggested starting these power supplies one by one or using the remote control function of switching power supply to turn them on/off.
