AC OUTPUT VOLTAGE ADJUSTMENT
Use this function to modify the voltages of the individual output phases of a specific power
module.
The phase voltage can be adjusted upward or downward by up to 15 V.
Each power module’s output voltage phases are calibrated before the UPS leaves
the factory, but over time or due to environmental factors the UPS’s output
voltage may drift slightly.
