DC-OK
DC-OK Signal is a TTL level signal, referenced to pin2(DC-OK GND). High when PSU turns on.
3+S
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.
4-S
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.

GND
This pin connects to the negative terminal(-V). Return for DC-OK signal output.
