Power Module
The Power Module maintains the condition of
power in the
Nfinity
UPS. Each module is an
independent 4-kVA unit, consisting of a power
factor corrected rectifier, 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.
Battery Module
The Battery Modules provide back-up power in
the event of input utility failure. Each module
contains a quantity of ten individual 12-volt 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 back-
up time and/or redundancy. Modules may be
added or replaced on-line with no interruption or
danger to the connected equipment.
