300W Single Output Medical Type
Auxiliary voltage output, 4.75~5.25V, reference to pin 2(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".
Remote control ground.
This pin connects to the negative terminal(-V). Return for DC-OK signal output.
Turns the output on and off by electrical or dry contact between pin 4 (RC-), Short: Power OFF, Open: Power ON.
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.
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.
