Functional Manual
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.
Built-in Resistor Ri (ohm)

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 RO 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 RO.
