Input/Output Voltage Convention

The SU5000R5T-TF3 is listed as a 208V Input and 120/208V Output. This raises several questions:

1) Since it has a 3-blade input plug (NEMA L3-30P), I'm assuming this is a single phase supply, fed from a 2-pole circuit breaker on a 3-phase building supply. The 3rd blade would need to be ground. Is this correct?

2) It lists output availability as 120/208V. The 120V is covered by the NEMA 5-15R and NEMA L5-20R receptacles. Since the 208V output receptacles have only 3 blades (L6-20R), I'm assuming they are also 208V single phase only (2-hot blades and a ground blade). Is this correct?

If I need a true 3-phase 208Y/120 output, what is the closest APC model that would have around 5000 VA capacity range? Ideally, I'd prefer a rack-mount unit, but this might not be available.

The SUA2200 and SUA2200RM2U both come standard with a NEMA 5-20P as the units' standard input plug.

Are there options for using a NEMA 5-15P?

tm13play,

The 2200 VA unit use a NEMA 5-20P because a 15A plug cannot achieve 2200VA, and therefore requires the 20A plug and power source. If you only have NEMA 5-15 Receptacles available, the largest UPS you can use on each 15A circuit would be any 1500VA SmartUPS.
