Power supply 160 mA, 320 mA, 640 mA, 1280 mA with integrated choke
Operation with emergency power systems
The power supply can be used in combination with centrally supplied emergency power sys-
tems. In this way, the function of the KNX system and the control of the most important func-
tions can be ensured in emergency operation.
Statutory and standard specifications for emergency power and emergency lighting sys-
tems vary from country to country. In any event, the user / technical planner must check
whether the specific specifications are observed.
Cable lengths
For KNX line segments and power supplies the following rules apply:
–
Bus line length per lin segment: Max. 1000 m
–
Bus line length between power supply and KNX bus subscriber: Max. 350 m
–
Bus line length between two KNX bus subscribers: Max. 700 m
