Current sharing signal. When units are connected in parallel, the CS pins of the units should be connected to allow current balance
between units.
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.
Return for RC+ signal input.
Turns the output on and off by electrical or dry contact between pin 4 ( RC+) and pin 3 (RC-). 0~0.8V: Power ON, 4~10V: Power OFF.
This pin connects to the negative terminal (-V). Return for DC_OK signal output.
DC-OK signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on.
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.
