PRODUCT DESCRIPTION
The UZK24.262 battery module utilizes two or four non-spillable
maintenance-free VRLA lead-acid batteries (connected in series) that are
assembled in one package with all the required wiring included.
Connector terminals for the paralleling of 2 batteries are included too.
The UZK24.262 comes with the sensor board UZW24.100 which contains
a temperature sensor, fuses for 2 to 4 batteries plus an auto-resett abl e
fuse which is suitable for balancer currents up to 2.5A. This fuse protects
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 th e
sensor board is optional, the DC-UPS will also function without the
sensor board installed.
The battery module is available in four different options. It can be
ordered as UZK-module with batteries or as UZO-module without
batteries, so these can be procured separately and installed at a l at er
date to avoid outdated batteries. Both modules contain the connection
board and wiring kit UZW24.100.
The extension kits can be ordered as UZK24.262-E1 with batteries or as
UZO24.262-E1 without batteries for the paralleling of a second batte ry
pack. Each module contain battery terminal covers and ring cable lugs.
