The battery module includes a monitoring and
protection board. This board contains a
temperature sensor and a center-tap connection
with an auto-resettable fuse to protect the center-
tap wire between the battery module and the DC-
UPS control unit.
The sensor board enables to monitor and charge
the two batteries individually and precisely,
extending the service life of the batteries and
making matching of replacement batteries
unnecessary.
Usage of the sensor board is optional, the DC-UPS
will also function without the sensor board
installed.
