INTRODUCTION AND SYSTEM DESCRIPTION

Congratulations on your choice of the Liebert UPStation GXT™ 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, which may interrupt computer operations, cause data loss, or even damage equipment. The UPStation GXT™ protects equipment from these disturbances. The UPStation GXT™, 208 VAC models comes in nominal power ratings of 1800 or 2700 VA. Complete specifications appear near the end of this section. The UPStation GXT™ is a compact, “on-line” UPS. An “on-line” UPS continuously conditions and regulates its output voltage, whether the utility power is present or not. It supplies connected equipment with clean sinewave power. Sensitive electronic equipment operates best from sinewave power. For ease of use, the UPStation GXT™ contains a light emitting diode (LED) display to indicate either “load percentage” or “battery capacity” depending upon the mode of operation. It also provides self diagnostics, a combination On/Alarm Silence/Manual Battery Test button, a combination Off/Bypass button, and two levels of alarms when the unit is operating on battery. The UPStation GXT™ has an interface port for communications between the UPS and a LAN server or other computer system. This port provides detailed operating information including voltages, currents, and alarm status to the host system when used in conjunction with Liebert SiteNet® software. SiteNet® software can also remotely control UPS operation.

CAUTION: This equipment has been tested and complies with limits for a Class A digital device, pursuant to Subpart B of Part 15 of FCC rules. These limits provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy. If it is not installed and used in accordance with the instruction manual, it may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, which the user must correct at his own expense.

TRANSIENT VOLTAGE SURGE SUPPRESSION (TVSS) AND EMI/RFI FILTERS

These 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.

RECTIFIER/POWER FACTOR CORRECTION (PFC) CIRCUIT

In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC power to regulated DC power for use by the inverter, while ensuring that the waveshape of the input current used 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, and 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 UPStation GXT™.

INVERTER

In normal operation, the inverter utilizes the DC output of the power factor correction circuit and “inverts” it into precise, regulated sinewave AC power. Upon a utility power failure, the inverter receives its required energy from the battery through the DC-DC converter. In both modes of the operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output power.

BATTERY CHARGER

The battery charger utilizes energy from the utility power and precisely regulates it to continuously “float” charge the battery system. The battery system charges whenever the UPStation GXT™ is plugged in.

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 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.
