1000W Single Output Power Supply
RSP-1000 series
Function Description of CN50
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 G-AUX _{Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V).}
4
5V-AUX
Auxiliary voltage output, 4.6~5.25V, referenced to pin 3(G-AUX). The maximum load current is 0.5A. This output has the built-in oring
diodes and is not controlled by the "remote ON/OFF control".
5
DC_OK
Open collector signal, referenced to pin11,12(GND). Low when PSU turns on. The maximum sink current is 10mA and the maximum
external voltage is 5.6V.
6 ON/OFF _{Turns the output on and off by electrical or dry contact between pin 6 ( ON/OFF) and pin 2 (-S). Short: Power ON, Open: Power OFF.}
7
CS
Current sharing signal. When units are connected in parallel, the CS pins of the units should be connected to allow current balance
between units.
8
Vco Short connecting between Vco (pin8) and Vca (pin10) if output voltage trim function is not used.
9
Vci
Connect to external DC voltage source for output voltage triming, referenced to pin 2 (-S). Output voltage can be trimmed between
40 ~ 110% of the rated output voltage.
10
Vca
Connect to external resistor (1/8W) for output voltage triming. Output voltage can be trimmed between 40 ~ 110% of the rated output
voltage. Please refer to function manual for details.
11,12 GND These pins connect to the negative terminal (-V). Return for DC_OK Signal output.
Function Manual
1."Remote ON/OFF" and "Output voltage trim" functions are not used.
The power supply unit will have no output if the shorting connector (accessory comes along with the PSU) is not assembled. It contains
two shorting wires : one is from ON/OFF (pin6) to -S (pin2) and the other is from Vco (pin8) to Vca (pin10).
