1000W Single Output DC-DC Converter
SD-1000 series
Function Description of CN51
Pin No. Function Description
1
+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.
2
-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.
3
O/P OK
Open collector signal, referenced to pin4(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum
external voltage is 13V.
4
GND These pins connect to the negative terminal (-V).
5
AUX Auxiliary voltage output, 10.8~13.2V referenced to pin6(AUXG).The maximum load current is 0.25A.
6 AUXG Auxiliary voltage output ground. The signal return is isolated from the output terminals(+V & -V).
