The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be twisted in pair to 1 +S minimize noise pick-up effect. The maximum line drop compensation is 0.5V. 2 3 4 5 6 -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. Open collector signal, reference to pin4(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum O/P OK external voltage is 13V. GND RC RCG These pins connect to the negative terminal (-V).

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) +Vo +Vo -Vo -Vo +V ADJ.
