Important info about using Multi Rail Power Supplies

28 June 2017

When using a Multi-Rail power supply you need to ensure all outputs have a load that falls within the stipulated current range, shown in the data sheet.

Failure to do so will result in the power supply not working correctly.

The below table is an extract from the data sheet for the Mean Well RQ-125B power supply.  In the table you can see the current range for each of the outputs (channels). The load on each of the outputs must fall within the stipulated range.

With this particular model output channel 4 is the only output that doesn’t need to have a load on it.

All others must have a suitable load on them in order for the power supply to work correctly.
