The UZK24.121 passive battery module utilizes two non-

spillable

maintenance-free

lead-acid

batteries

(connected in series), that are assembled in one package

with all the required wiring included.

The battery module includes the monitoring and

protection board UZS24.100. 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. Connecting the center-tap wire to the DC-UPS

control unit enables all the benefits of the PULS 1-

Battery-Concept. This makes the use of matched

replacement batteries unnecessary and allows a precise

battery charging and testing which results in the

longest possible battery life.

The UZK24 battery module is available in two different

options. It can be ordered with assembled batteries or

as a battery bracket without batteries, allowing for

different battery options. The mounting bracket option

also allows the batteries to be assembled just in time,

avoiding outdated batteries due to limited shelf life.
