Question

Are there models available that support series operation?

Answer

The following table shows the models that support series connection of outputs.

Models Supporting Series Connection of Outputs

Model	Power ratings	Rated output voltage
S82K	90, 100 W	24 VDC
S82J	100 W	5, 12, 15, 24 VDC
S82J	50, 150, 300, 600 W	24 VDC
S8TS	25, 30, 60 W	5, 12, 24 V
S8VS	15, 30, 60, 90, 120, 180, 240 W	24 VDC
S8VM	15, 30, 50, 100, 150, 300, 600, 1,500 W	5, 12, 15, 24 VDC

Series operation cannot be used with Power Supplies that are not listed in the table above. If Series operation is used with those Power Supplies, the output may not start in one of the Power Supplies and its internal circuits may be damaged if left in that state.

When using series operation with Power Supplies listed in the preceding table, the Power Supplies may have different output capacities and output voltages, but the current flowing through the load must be less than the rated output current of the Power Supply with the lower output capacity.

If an S82J-05024[][], S82J-10024[][], S8TS-02505[], or S8VS Power Supply is being used and the load is shorted, a reverse voltage may be generated in the Power Supply, damaging the Power Supply or causing it to fail.

Diode type: Schottky barrier diode

Dielectric strength (VRRM): At least twice the Power Supply's rated output voltage

Forward current (IF): At least twice the rated output voltage of the Power Supply
