5 DC-OK
DC-OK Signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on.
7 +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.
8 -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.
6 GND
This pin connects to the negative terminal(-V). Return for DC-OK signal output.

AUXG
Auxiliary voltage output, 4.75~5.25V, referenced to pin 4(AUXG). The maximum load current is 0.3A. This output has the built-in oring
diodes and is not controlled by the "remote ON/OFF control".
Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V).
