Function

Description

C1

-5VSB

This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.

C2

+5VSB

Stand by voltage output ground 4.5~5.5V, referenced to pin C1(-5VSB). The maximum load current is 0.6A.

C3

GND

This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.

C4

DC OK

DC-OK Signal is a DC output, referenced to pin C3(DC-OK GND).

C5

-RC

This pin connects to the negative terminal(-V). Return for DC-OK and -RC signal output.

C6

+RC

Turns the output on and off by electrical or dry contact between pin C5 (-RC), Short: Power OFF, Open: Power ON.

C7

-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 0.3V.

C8

+S

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.
