Remote On/Off Function
This feature 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 off. Pin 15 is referenced to the (-) output voltage.
The open-loop voltage between pin 16 and pin 15 can be up to 18V,
the maximum current, when in remote OFF 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.
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 shut-down function has no safety feature included.
