Understanding UPS Operation

6.1 Looking Inside the UPS System

The Powerware 9390 UPS is a continuous duty, solid-state, transformerless (at 208 and

480 Vac), three-phase, true online system that provide conditioned and uninterruptible AC

power to the UPS systems output. The UPS supports process control, data processing,

telecommunications/PBX, research, and non-patient medical equipment. The Powerware

9390 UPS maintains power to the critical loads during commercial electrical power

brownout, blackout, overvoltage, undervoltage, and out-of-tolerance frequency conditions.

The basic system consists of a rectifier, battery converter, inverter, monitoring/operation

control panel, integrated communications server, and microprocessor-controlled (DSP)

logic.

In this manual, the power required by your equipment is called the

critical load

. The UPS

supplies the critical load with conditioned power that is synchronized with your utility

power. Figure 6-1 shows the main elements of the UPS.
