Looking Inside the UPS System
The Powerware BPIV is a continuous duty, solid-state, transformerless (at 208
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 BPIV 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 charger, DC booster, 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 7---1 shows the main elements of the UPS.
