Remote ON/OFF Function
You can remotely control the power supply unit to turn
ON/OFF by using an external DC source. Follow the DC
power source voltage and current limiting defined in the
table below.

Notes
1. Remote ON/OFF circuits are isolated from input, output and PE.
2. Please check if the polarity of the wire connector is the same as the external DC source. If not, the power would not turn on and the
internal components may be damaged.
3. You do not need an external resistance R
O
for current limit while the output voltage of external DC source is within the range of 5-
12.5V. If the output voltage exceeds 12.5V, please use the following equation for the value of current limit resistance R
