Battery Reserve System
Introduction A battery reserve system is a key ingredient for the CPS product line. A
power plant provides a primary voltage of -48Vdc or +24Vdc that drives
the switches of transmitting customer equipment. At the same time, the
power plant provides float and recharge capability for the battery
reserve system. If an ac power failure occurs, the batteries provide
power to the customer equipment until the ac can be restored.
Types of Batteries Typically, a CPS plant will use Lucent Technologies 12IR125 batteries.
As alternatives, CPS plants may be equipped with other valve-regulated
(VR) batteries. Up to four strings of VR-type batteries or equivalent
general trade batteries may be connected directly to a 48V CPS shelf.
IR30/IR40
Batteries
Up to four J85504D-1 IR battery modules may be connected directly to
a -48V CPS shelf. These modules interface with the CPS Bulk
Distribution Unit to provide the low-voltage disconnect and battery
thermal monitoring features inherent in the CPS plant. J85504D-1
battery modules include the following:
• Space for two -48V battery strings of IR30or IR40 batteries
• Output fusing (with fuse alarm signalling) at 40 amperes per
J85504D-1 module
• Battery interconnection
• Thermistor assembly (847050010)
• Alarm wire set (847157674)
• Temperature wire set (847157716)
