2.1 General Description

The Liebert® Trinergy™ Cube provides continuous, high-quality AC power to business-critical equipment, such as
telecommunications and data processing equipment.
The Trinergy Cube supplies power that is free of the disturbances and variations in voltage and frequency common to utility
power, which is subject to brownouts, blackouts, surges and sags.
The Trinergy Cube utilizes the latest in high-frequency, double-conversion pulse-width modulation technology and fully
digital controls to enhance its reliability and increase the ease of use.
As shown in the following figure, the AC utility source is input at the rectifier and the rectifier converts the AC utility into DC
power. The inverter converts that DC power from the rectifier or DC power from the DC source-into AC power for the load.
The DC source will power the load through the inverter in the event of a power failure. The utility source can also power the
load through the static bypass. If maintenance or repair of the UPS is necessary, the load can be switched without
interruption in service to the optional maintenance bypass.
