Guide Specifications
1.3.3.2 AC Output, UPS Inverters
A.
Voltage Configuration:
50/60Hz, single-phase, 3-wire-plus-ground.
Default setting 120/208V. Output L-N voltage shall be selectable via the included UPS configuration
program. Optional settings shall be 100/200V, 110/220V, 115/230V, 120/208V, 120/240V or 127/220V. The
UPS shall adjust sinewave amplitude and/or phase-angle relationship of the inverters to produce the selected
voltage to match the input.
Note
: At 100/200V setting, the UPS shall be derated to 80% of the rated 120/208V capacity; at 110/220V, the
UPS shall be derated to 90% of the rated 120/208V capacity.
B.
Voltage Regulation:
L1-N and L2-N: ±3% steady state.
L1-L2: ±5% steady state.
C.
Frequency Regulation:
