Data Sheet

5CS
Current sharing signal. When units are connected in parallel, the CS pins of the units should be connected to allow current balance
between units.
7
DC-OK
DC-OK signal is a TTL level signal, referenced to pin8(DC-OK GND). High when PSU turns on.
9+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.
10 -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.
6,8
GND
This pin connects to the negative terminal(-V). Return for DC-OK signal output.

AUXG
Auxiliary voltage output ground.
Auxiliary voltage output, 4.75~5.25V, referenced to pin 1(AUXG). The maximum load current is 0.3A. This output is not controlled by the
"remote ON/OFF control".
The remote sensing compensates voltage drop on the load wiring up to 0.5V.
