Battery Reserve System
Introduction
A battery reserve system is a key component for a reliable power system. The CPS6000 provides a
primary voltage of -48V
capability for the battery reserve system. If an ac power failure occurs, the batteries provide power to
the load equipment until the ac can be restored.
Types of Batteries
CPS6000 may be used with valve-regulated lead-acid (VRLA) batteries. Up to four strings of VR-type
batteries or equivalent general trade batteries may be connected directly to a CPS6000 shelf.
Certain Nickel-Cadmium (Ni-Cd) and Lithium-Ion batteries may also be used with the CPS6000. Please
contact your sales representative for details. CPS6000 is also compatible to Flooded lead-acid
batteries.
See Appendix D for detailed descriptions of battery related functions; float and boost charging,
thermal compensation, and system battery test functions
