Introduction 2.0 INTRODUCTION Congratulations on your choice of the Liebert UPStation GXT 2U Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment. Upon generation, AC power is clean and stable. However, during transmission and distribution it may be subject to voltage sags, spikes, or complete power failure that may interrupt computer opera- tions, cause data loss, or even damage equipment. The UPStation GXT 2U protect

Major Components 3.4 BATTERY CHARGER The battery charger utilizes energy from the utility power and pre- cisely regulates it to continuously float charge the batteries. The bat- teries are being charged whenever the UPStation GXT 2U is plugged in, even when the UPS is not turned on. 3.5 DC TO DC CONVERTER The DC to 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
