Liebert 700-3000 VA user manual DC to DC Converter, Battery, Dynamic Bypass

DC TO DC CONVERTER

The DC-DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.

BATTERY

The UPStation GXT™ employs valve regulated, nonspillable, lead acid batteries. At typical room temperatures and with the UPS float charging, the battery system will last many years. Optional external battery cabinets are available to provide extended run times for the rack-tower (RT) models. For battery run times, refer to the Typical Battery Discharge Curves.

DYNAMIC BYPASS

The UPStation GXT™ 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, over temperature, or UPS failure condition, the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an alarm and an illuminated Bypass LED (other LED’s may be illuminated to indicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass power, press the Off button once.

NOTE: The bypass power path does NOT protect the connected equipment from disturbances on the utility supply.
