1. INTRODUCTION

1-1. Picture

UPS This UPS series is a dual conversion system with sine wave output. Supply continuous, stable, and clean
power for commercial and industrial needs. When utilities are lost, the UPS system will use batteries to
produce uninterrupted output.
The system implements an advanced digital controller to control the dual conversion system, and an isolated
transformer at the output to protect the load and the UPS itself. The UPS also has an easy-to-use LCD
interface and multiple communications including SNMP, Modbus, RS-232 and smart slots. Using software,
these UPSs can provide a complete power solution with remote monitoring and control.

1-2. Basic Structure

The entire system consists of REC module, INV module, static bypass, maintenance bypass and battery
controller. Output from the UPS is generated by a line insert or bypass with two SCRs operated in parallel.
The basic structure is shown as below:
