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.

The Battery Modules provide back-up power in the
event of input AC Mains 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.
