Technical data
The battery module 6180/12 is a lead-gel
battery for maintaining the Busch-Installati-
onsbus KNX system voltage in case of a mains
failure. The battery module can only be used
in combination with the uninterruptible KNX
Power supply 6180/11. The battery module
can maintain the KNX voltage for a minimum
of 10 minutes at rated current. Total backup
time depends on the bus load. In order to mo-
nitor the charging voltage, a PTC temperature
sensor is integrated in the battery module.
The battery module is protected against short
circuit and excessive charging currents by an
integrated fuse.
Due to the limited life of battery devices, the
battery module should be replaced approx.
every four years in order to guarantee the
minimum backup time! Used battery modu-
