UPS power rating
The maximum attainable UPS system power rating is determined by the size of
the UPS cabinet frame. The number of UPM power modules determines the
nominal power rating of the UPS. If upgradeability is required, the system static
bypass should be chosen according to the future maximum load rating, and the
number of UPMs is chosen according to the capacity requirements on day one.
The following UPS configurations with different static bypass sizes and number
of UPMs are possible:
