Looking Inside The Ups System - Eaton 93PR Installation And Operation Manual

2.1. Looking Inside the UPS System

The system level static bypass in the 93PR series UPS determines the attainable output power of the
UPS. The static bypass line consists of static switch and a backfeed protection isolation device connected
in series. In addition, there is a system level control unit that constantly monitors the power delivered
through the bypass line or to the input of the UPS. Transfers to static bypass are seamless and performed
automatically by the system as needed, for example, in case of an extended system overload.
Each UPM power module includes a rectifier, battery converter, inverter and independent controls. The
UPM is hot swappable (Hot Swap), Each UPM is able to operate and share the load independently,
despite the status of the other UPMs.
