1.2Major Components

Rectifier

Converts AC input voltage to DC voltage. The rectifier uses IGBT (Insulated G a t e

 

Bipolar Transistor) power transistors and a Pulse Width Modulated (PWM)

 

technique to provide input power factor correction and to minimize any harmonic

 

reflected onto the input power lines.

Inverter

Converts DC voltage from the rectifier or from the batteries into AC output voltage

 

to maintain the attached load. This module uses the IGBT technology to provide

 

digital power quality.

Static Switch

Automatically supplies the attached load from the bypass source when the inverter

 

is off.

Battery System

Stores energy for utilization by the inverter and attached load in the event that utility

 

AC power is lost or is of unacceptable quality.

1.3Single Line Diagram

During normal operation, the utility power (Main input) is supplied to the UPS rectifier. The rectifier converts the AC power to DC that is supplied to the inverter. The inverter converts the DC voltage to three-phase regulated AC voltage, which is supplied to the attached load.

During power failure conditions, the inverter is supplied by the stored energy in the battery system, and the load is powered continuously with no interruption.

The Galaxy 4000 UPS is designed for internal operation of 208VAC input and output. External batteries, and an output distribution panel may be contained in auxiliary cabinets similar in design to the Galaxy 4000 cabinet. Batteries or external maintenance bypass circuit breakers may also be contained in third party cabinets or wall mounted units.
