The Liebert GXT3 protects equipment fromthese disturbances.The Liebert GXT3 is a compact, on-line UPS. An on-line UPS continuously conditions and regulatesits output voltage, whether utility power is present or not. It supplies connected equipment withclean, sinewave power. Sensitive electronic equipment operates best from sinewave power.For ease of use, the Liebert GXT3 features a light-emitting diode (LED) display to indicate both loadpercentage and battery capacity. It also provides self-diagnostic tests, a combination ON/AlarmSilence/Manual Battery Test button, a Standby/Manual Bypass button and a configuration program.The Liebert GXT3 has a Liebert IntelliSlot port for communication between the UPS and a networkserver or other computer systems. This port provides detailed operating information includingvoltages, currents and alarm status to the host system when used in conjunction with LiebertMultiLink . Liebert MultiLink can also remotely control UPS operation.4
System Description2.0SYSTEM DESCRIPTIONOutputInputStaticBypassL1L2NL1TVSS erterBatteryChargerBatteryG2.1NGTransient Voltage Surge Suppression (TVSS) and EMI/RFI FiltersThese UPS components provide surge protection and filter both electromagnetic interference (EMI)and radio frequency interference (RFI). They minimize any surges or interference present in the utility line and keep the sensitive equipment protected.2.2Rectifier/Power Factor Correction (PFC) CircuitIn normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC power toregulated DC power for use by the inverter while ensuring that the waveshape of the input currentused by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: The utility power is used as efficiently as possible by the UPS. 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 bythe Liebert GXT3.2.3InverterIn normal operation, the inverter utilizes the DC output of the power factor correction circuit andinverts it into precise, regulated sinewave AC power. Upon a utility power failure, the inverterreceives its required energy from the battery through the DC-to-DC converter. In both modes of operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC outputpower.2.4Battery ChargerThe battery charger utilizes energy from the utility power and precisely regulates it to continuouslyfloat charge the batteries. The batteries are being charged whenever the Liebert GXT3 is connected toutility power.2.5DC-to-DC ConverterThe 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 at its optimum efficiency and voltage, thus increasing reliability.5
System Description2.6BatteryThe Liebert GXT3 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain batterydesign life, operate the UPS in an ambient temperature of 15 C to 25 C (59 F to 77 F). Optionalexternal battery cabinets are available to extend battery run times. For run times, see Table 14.2.7Dynamic BypassThe Liebert GXT3 provides an alternate path for utility power to the connected load in the unlikelyevent of a UPS malfunction. Should the UPS have an overload, overtemperature or any other UPSfailure condition, the UPS automatically transfers the connected load to bypass. Bypass operation isindicated by an audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated toindicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass,press the Standby/Manual Bypass button once and hold it for about 2 seconds.NOTEThe bypass power path does NOT protect the connected equipment from disturbancesin the utility supply.6
