Output Transformer Voltage Compensation

It is possible to compensate for an output transformer and balance the output voltage drop (0-3%).

  1. Disconnect the load from the UPS.

  2. Measure the voltage on the secondary side of the transformer at 0% load, and adjust the output voltage of the UPS manually via the Voltage compensation (%) setting to compensate for the voltage offset, if any .

  3. Connect the load to the UPS.

  4. Measure the voltage on the secondary side of the transformer again at X% load, and adjust the output voltage of the UPS via the Transformer voltage compensation (%) setting to compensate for the voltage drop in the transformer.

The transformer voltage compensation required at the specific load is used to make an automatic linear output voltage adjustment on the UPS according to the output load percentage.
