KNX Redundant Bus Power Supply with diagnostic function, 6SU MDRC, 640 mA.
Nominal current 640 mA, continuous current 960 mA, peak 1200 mA. KNX power supply with integrated choke.
Two integrated power supplies for redundancy. Mains voltage 230 V AC (separate FI circuits possible).
If one mains voltage or one of the internal power supplies fails, the KNX bus voltage keeps stable by the second power supply.
Failure message by a telegram. Short-circuit-proof. Overload safe.
With additionally choke free output. Integrated bus coupling unit with diagnostic function: Bus voltage, bus current, bus overload. Bus voltage failure/return. All events are stored with time stamp in a ring buffer. Read out of the ring buffer by 14 Byte telegram.
Safety functions to detect a failed device in the KNX line.
