Introduction

1.3.4Power Module

Each power module is an independent 4 kVA, 2.8kW unit, consisting of a power factor corrected recti- fier, battery charger and inverter, with associated monitoring and control circuitry. The modules are paralleled to provide greater capacity and/or redundancy. Modules may be added or replaced on-line with no interruption or danger to the connected equipment.

1.3.5Battery Module

Each battery module contains 10 individual 12-volt, 9 amp hour, valve-regulated (VRLA) battery blocks with associated monitoring and controls to isolate the Battery Module in the event of a battery failure. The modules are paralleled to provide greater capacity, backup time and/or redundancy. Mod- ules may be added or replaced on-line with no interruption or danger to the connected equipment, provided that the UPS is not operating on battery.
