2.Output OK signal
"Output 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 signal ;
the other is sending out a voltage signal.
2-1 Sink current :
The maximum sink current is 10mA and the maximum
external voltage is 13V.
2-2 Voltage signal :
Between O/P OK(pin3) and GND(pin4)

These pins connect to the negative terminal (-V).
Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be twisted in pair to
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
Positive sensing. The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be twisted in pair to
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
