450W Single Output with PFC Function
HRPG-450 series
Function Description of CN100
Pin No. Function Description
1
RC+ Turns the output on and off by electrical or dry contact between pin 2 (RC-), Short: Power OFF, Open: Power ON.
2
RC- Remote control ground.
3
AUX
Auxiliary voltage output, 4.75~5.25V, referenced to pin 4(AUXG). The maximum load current is 0.3A. This output has the built-in oring
diodes and is not controlled by the "remote ON/OFF control".
4 AUXG Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V).
5 DC-OK DC-OK Signal is a TTL level signal, referenced to pin6(DC-OK GND). High when PSU turns on.
6
GND This pin connects to the negative terminal(-V). Return for DC-OK signal output.
7
+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.
8
-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.
Function Manual
1.Remote Sense
The remote sensing compensates voltage drop on
the load wiring up to 0.5V.
