Single Operation:

1) Make sure that the front panel switch is set to “single Use.”

2) The output voltage can be increased by trim pot to compensate any cable losses.

Parallel Operation:

1) Make sure that the front panel switch is set to “single Use” on each power supply.

2) Adjust each power supply to the exact same output voltage with same load and cooling conditions.

3) Set the front panel switches to “Parallel Use.” Use the same wire length for each power supply (star connection) and energize all units at the

same time to avoid triggering overload protection.

Derate the maximum output power to 90% of nominal ratings.

For operation with more than three power supplies in parallel or series operation, please contact RECOM technical support for advice.
