Page 10: Chapter 1 - Introduction
CHAPTER 1 - INTRODUCTION 1.1 Introduction This modular UPS system utlizes an online double-conversion design and DSP-based digital control to supply stable, uninterrupted power for your critical loads. It eliminates damaging power surges and harmonic frequencies and regulates voltage to provide clean power to your devices. The key features of the modular UPS system are: •... -
Page 11: Fig 1-1: Single Unit Block Diagram
CHAPTER 1 - INTRODUCTION The 3-Phase UPS system provides the critical load (such as communication and data processing equipment) with high-quality, uninterruptible AC power. The power from the UPS is free from voltage and frequency variations and disturbances experienced at the mains AC input supply. This is achieved through high-frequency double-conversion. -
Page 12: Dual-Feed Input
CHAPTER 1 - INTRODUCTION 1.1.1 Dual-Feed Input Fig. 1-1 illustrates the 3-Phase UPS in what is known as the Dual-Feed configuration. In this configuration, the static bypass and maintenance bypass share the same independent bypass power supply and connect to the power supply through a separate switch. Where a separated power source is not available, the bypass and rectifier input supply connections are linked. -
Page 13: Parallel Ups Systems
CHAPTER 1 - INTRODUCTION 1.1.4 Parallel UPS Systems NOTICE Two UPS systems in a parallel system must have the same battery configuration. Each UPS system requires a separate battery cabinet. A parallel UPS system with multiple UPSs can be installed to provide a parallel capacity and/ or redundant system. -

Page 16: Battery Mode
CHAPTER 1 - INTRODUCTION 1.2.2 Battery Mode Upon failure of the AC mains input power, the inverter power modules, which obtains power from the battery, supplies the critical AC load. There is no interruption in power to the critical load upon failure. -
Page 17: Bypass Mode
CHAPTER 1 - INTRODUCTION 1.2.4 Bypass Mode If the inverter overload capacity is exceeded when in normal mode, or if the inverter becomes unavailable, the static transfer switch will perform a transfer of the load from the inverter to the bypass source, with no interruption in power to the critical AC load. Should the inverter be asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the load. -
Page 18: Parallel Redundancy Mode (System Expansion)
CHAPTER 1 - INTRODUCTION 1.2.6 Parallel Redundancy Mode (System Expansion) For higher capacity or higher reliability or both, the outputs of several 3-phase UPS systems can be programmed for direct parallel while a built-in parallel controller in each UPS system ensures automatic load sharing. -
