1. GENERAL DESCRIPTION
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avoiding outdated batteries due to limited shelf life.
