The UZK24 battery module is available in two different options. It can 
be ordered with assembled batteries (UZK24.071) or as a battery bracket without batteries (UZO24.071), allowing f
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outdated batteries due to limited shelf life. 
Battery voltage  DC 24V 
Battery capacity  7Ah 
Temperature sensor  PT1000 
Dimensions WxHxD  137x186x143mm

22.5.  UZK24.121 – 24V, 12AH BATTERY MODULE 
The UZK24.121 passive battery module utilizes two non-spillable 
12Ah maintenance-free VRLA 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-U
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.
