Description
Current Share Function Pins
This pin connects to the negative terminal (-V). Return for DC-OK signal output.
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 C4 (-RC), Short: Power OFF, Open: Power ON
DC-OK Signal is a DC output, referenced to pin 6 (DC-OK GND).
Stand-by voltage output ground 4.5~5V, referenced to pin C4 or C5 (GND). The maximum load current is 0.6A

3. Current Sharing
1. The difference of Vout among parallel units should be less than ±1%.
2. The power Pout should be less than 50%.
3. Three units is the maximum when in in parallel operation.
4. The power supplies should be connected in parallel to the load using short and large diameter wiring (twisted is ideal).
