The remote sensing compensates voltage drop on the
load wiring up to 0.5V.

3.DC_OK signal
"DC_OK" is an open collector signal.
It indicates the output status of the PSU. It can operate
in two ways : One is sinking current from external TTL
signal ; the other is sending out a TTL voltage signal.
3-1 Sink current :
The maximum sink current is 10mA and the maximum
external voltage is 5.6V.
3-2 TTL voltage signal :
Between DC- OK(pin9) and GND (pin10&11)
Between ON/OFF(pin1 3) and 12V-AUX(pin14)
