    1500, 2000 and 3000 VA. Complete model specifications appear at the end of this manual. The UPStation GXT 2U is a compact, “on-line” UPS. An on-line UPS con- tinuously conditions and regulates its output voltage, whether utility power is present or not. It supplies connected equipment with clean sinewave power.

  • Page 9: Major Components

    The amount of distortion reflected on the utility is reduced This results in cleaner power being available to other devices in the build- ing not being protected by the UPStation GXT 2U. 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.

  • Page 10: Battery Charger

    YNAMIC YPASS The UPStation GXT 2U provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature, or UPS failure condition, the UPS automatically transfers the connected load to bypass.
