    • The amount of distortion reflected on the utility is reduced. This results in cleaner power being available to other devices in the building not being protected by the Liebert GXT2U. NVERTER In normal operation, the inverter utilizes the DC output of the power factor correction circuit and inverts it into precise, regulated sinewave AC power.
