FUNCTION DESCRIPITON of CN4 :

Pin No.

Function

Description

C1

+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. (max.)

C2

-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. (max.)

C3

+RC

Turns the output on and off by electrical or dry contact between pin C4 (-RC), Short: Power OFF, Open: Power ON.

C4

-RC

Remote control ground.

C5

DC-OK

DC-OK Signal is a DC output, referenced to pinC6(DC-OK GND).

C6

GND

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

C7

+5V SB

Stand by voltage output ground 4.5~5.5V, referenced to pin C8(-5V SB). The maximum load current is 0.6A.

C8

-5V SB

Stand by voltage output ground.

FUNCTION MANUAL :
