Power Supply Topic: Models with Serial Operation

FAQ No. FAQ01942

Question

Are there models available that support serial 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
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

Serial operation cannot be used with Power Supplies that are not listed in the table above. If serial 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 serial 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
