Frequency Converter Mode

In frequency converter mode the UPS is able to convert the frequency of the input source to a different frequency on the UPS output.

NOTE: Frequency converter mode must be configured by Schneider Electric during service configuration.

The possible input/output frequencies are 50/50 Hz, 50/60 Hz, 60/50 Hz and 60/60 Hz. This is set under output frequency.

When the UPS is configured as frequency converter static bypass is not available:

  • Transfer to static bypass is disabled

  • Alarms and events related to the static bypass switch and the bypass source are disabled (not shown)

  • References to the static bypass switch and the MBB are removed from the mimic diagram in the display and UPS Tuner

  • Guided sequences are changed to support startup and shutdown of the UPS with no bypass available

It is possible to run battery self-test and battery runtime calibration even when there is no bypass available.

NOTE: In frequency converter mode the capacitor lifetime is reduced by 40%.
