2 Overview

This chapter briefly introduces the features, design concept, parallel system, operation mode, battery management, and
battery protection of the Liebert APM Plus 250 kVA UPS (UPS for short).

2.1 Features

UPS is connected between a critical load (e.g. a computer) and mains power to provide high quality power for the loads.
UPS has the following advantages:

•

Augment power quality

UPS protects its output against the input power change through the intelligent controller.

•

Provide mains failure protection

If the input power fails, the UPS will work in battery mode, and the power supply to the loads will not be interrupted.

2.2 Design Concept

2.2.1 System Design

This section introduces the working principle of the UPS single module. The UPS adopts AC-DC-AC converter (as shown in
Figure 2.1 on the next page). The first stage conversion (AC-DC) adopts three-phase high frequency rectifier to convert the
three-phase input voltage into stable DC bus voltage.
