Description
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
Stand by voltage output ground 4.5~5.5V, referenced to pin C1(-5VSB). The maximum load current is 0.6A.
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
DC-OK Signal is a DC output, referenced to pin C3(DC-OK GND).
This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.
Turns the output on and off by electrical or dry contact between pin C5 (-RC), Short: Power OFF, Open: Power ON.
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 0.3V.
Positive 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 0.3V.
