1.1Overview

This equipment is a high performance line interactive uninterruptible power source (UPS) designed to provide clean, reliable AC power to computer loads. The UPS's line interactive circuit topology, illustrated below, offers excellent efficiency, on-line voltage regulation and fast utility fault response.

The UPS’s DC-to-AC inverter is always connected to the output and when operating on- line, a portion of the inverter circuitry is put to work “in reverse” to continuously maintain optimum float charge on the battery. The inverter circuitry also acts to protect the load from surges and EMI/RFI noise as part of an advanced hybrid surge suppres- sion and filtering network. A unique mode of operation, named SmartBoost, serves to regulate the load voltage by compensating for brownouts or sags. This is accomplished without the need to draw power from the UPS’s battery. In anticipation of utility failure, the UPS continuously monitors the line and prepares the inverter frequency for synchronous transfer of the load. Upon occurrence of utility voltage failure such as a blackout, severe brownout or an overvoltage condition, the UPS transfers the load to power derived from the battery. Transfer to the "on-battery" mode of operation takes place typically within 2 milliseconds. The inverter's output voltage waveshape is a low distortion sine wave. Resynchronization and retransfer to on-line operation is auto- matic upon recovery of the line voltage to within normal limits.
