In the observation, three main criteria need to be considered:
1.
The peak power of the UPS (for approx. 3 seconds) should be ≥ 600 W.
2.
With the use of the transformer, the UPS must be designed as an online double
converter. Classification: VFI (according to IEC 62040-3)
3.
The energy storage of the UPS must be adapted to the entire drive system and the time
to be bridged.
