9. REMOTE ON / OFF FUNCTION
This feature is available only for the CP20.241-V1 and allows to switch-off the power supply output
with a signal switch or transistor. A link between pin 15 and 16 turns the power supply on. Pin 15 is
referenced to the (-) output voltage.

Remote
ON/OFF
The open-loop voltage between pin 16 and pin 15 can be up to 18V. The maximum current, when in
remote ON mode, can be up to 2.5mA.
The threshold level to switch-off the output is typically 5V and the turn-on threshold is typically 9V.

ON/OFF
When multiple power supplies are connected in parallel, pin 15 and pin 16 are also allowed to be
paralleled to control all units with the same switch or transistor.
Please note: The remote ON/OFF function has no safety feature included.
