Introduction
Battery Charger Modules
NOTE One battery charger module is required for every five EBC120s. A 12-slot
cabinet with 37 battery strings also requires one battery charger module.
The optional battery charger module is designed to provide additional
current for faster recharging of UPS battery modules in systems with
many batteries. It is capable of providing up to 20 amperes of current for
optimum charging, based upon the condition and number of batteries in
the system.
The battery charger module is similar in appearance to a power module.
The primary difference is the light-purple colored front label. It can be
plugged into any UPS cabinet slot above the battery modules.
The battery charger module operates in automatic modes within the UPS
cabinet under control of the UPS power modules. It communicates
through a controller area network (CAN) bus with the power modules.
The power modules monitor and control the battery charger. Alarm
conditions detected by the battery charger module are logged and
announced by the UPS system (refer to the UPS user's guide). Normal
output voltage is 133 Vdc.
