    2 Overview This chapter briefly introduces the features, design concept, parallel system, operation mode, battery management and battery protection of the Vertiv™ Liebert® EXM2 UPS 100kVA~250kVA (UPS for short). 2.1 Features The UPS is connected between a critical load (e.g. a computer) and mains power to provide high quality power for the loads.

  • Page 16: Design Concept

    Vertiv™ Liebert® EXM2 UPS User Manual 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 below). The first stage conversion (AC-DC) adopts three-phase high frequency rectifier to convert the three-phase input voltage into stable DC bus voltage.

  • Page 17: Bypass

    Vertiv™ Liebert® EXM2 UPS User Manual The UPS has its own battery charger and adopts advanced temperature compensation technology to effectively prolong the battery service life. The inverter adopts three level T-type IGBT topology and uses advanced SVPWM control technology to derive the stable AC voltage from the DC bus voltage.

  • Page 18: System Control Principle

    In case of inverter failure and output fuse blowout, the load will automatically transfer to the bypass, and the output power supply will not be interrupted. In this situation, please contact the local customer service center of Vertiv for technical support.
