SL-23188_REV1_08-10 5 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: ±3.5Hz synchronized to utility / mains.
±0.1Hz free running or on battery operation.
D. Frequency Slew Rate: 1.0Hz per second maximum
E. Load Power Factor Range: 0.65 lagging to 1.0 (unity)
F. Voltage Distortion: Sinusoidal Waveform; ≤3% total harmonic distortion (THD) into a 100% linear load;
≤5% THD into a 100% non-linear load with a crest factor ratio of 3:1.
