Battery Charger Modules
NOTE
One battery charger module is required whenever one or two EBCs are used.
A 9 kVA UPS system with 13 or 14 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 (see “Alarm Log” on page 38). Normal
output voltage is 133 Vdc.
