450W Single Output with PFC Function
HRP-450 series
Function Description of CN100
Pin No. Function Description
1 DC-OK DC-OK Signal is a TTL level signal, referenced to pin2(DC-OK GND). High when PSU turns on.
2
GND This pin connects to the negative terminal(-V). Return for DC-OK signal output.
3
+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.
4
-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.
