480 Watts
FUNCTION DESCRIPITON of CN4 :
Pin No.
Function
Description
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.)
C1
+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.)

Turns the output on and off by electrical or dry contact between pin C4 (-RC), Short: Power OFF, Open: Power ON.
Remote control ground.
DC-OK
GND
DC-OK Signal is a DC output, referenced to pinC6(DC-OK GND).
This pin connects to the negative terminal(-V). Return for DC-OK signal output.
Stand by voltage output ground 4.5~5.5V, referenced to pin C8(-5V SB). The maximum load current is 0.6A.
Stand by voltage output ground.
+5V SB
