1.1 Product Overview
The ACS HP Series Battery Charger is a modular, switched mode AC-DC conversion design,
consisting of one or more Cordex rectifier modules coupled with a Cordex CXC microprocessor
controller. This charging system possesses a unity power factor with efficiency greater than
93%, a negligible THD input level, and clean output power, providing reliable, quality DC power
for many years.
The 4RU shelf of the unit accommodates up to five, hot swappable Cordex 4.4 kW rectifiers,
which allows for N+1 or N+N redundancy capability, as well as expansion capability up to
175A output capacity. The hot swappable design of the rectifiers allows them to be inserted or
removed from the shelf without requiring the power to be cut to or from the system or the load.
Configuration, monitoring, and control of the charging system is provided by the Cordex CXC
controller, either locally via the CXC touch screen display or remotely via an ethernet or RS-
232 connection and an internet browser (DNP3 Level 2 communication is also available as an
optional feature). Battery management, data logging, and temperature compensation are just
some of the standard features supplied by the CXC controller.
Other standard features of the ACS HP series battery charger include high interrupting current
input and output circuit breakers, AC and DC surge protection, common Form C alarm relay
contacts, and high voltage shutdown.
