Chapter 1 Overview
This section provides a short introduction to the Liebert S600E 10kVA - 20kVA UPS (hereafter referred to as “the
UPS”), covering features, design concept, parallel system, operating mode, battery management and battery
protection.
1.1
Features
The UPS is connected between a critical load (e.g. a computer) and the mains power supply to provide high quality
power for the loads. The UPS provides the following advantages:
Increased power quality
The UPS protects its output against the variations in the input power supply by means of the intelligent controller.
Improved noise rejection
Due to the use of AC-DC-AC conversion, noise on the input power supply is effectively filtered, so that the load is
provided with a “clean” power supply.
Mains failure protection
If the input power fails, the UPS switches to battery operating mode so that the power supply to the loads is not
interrupted.
Compatible with two output modes
3-in 3-out (factory default) and 3-in 1-out (by installing an optional 3-in 1-out copper bar kit). Only authorized
personnel are permitted to change the wiring method and modify the corresponding parameters using the VERTIV
setting software.
1.2
Design Concept
System Design
This section introduces the working principle of the single UPS module. The UPS adopts AC-DC-AC conversion (as
shown in Figure 1-1). The first stage conversion (AC-DC) uses a three-phase, high frequency rectifier to convert the
three-phase input voltage into a stable DC bus voltage.
