Redundant Bus Power Supply with diagnostic function, 6SU MDRC, 640mA

Nominal current 640mA, continuous current 960mA, peak 1200mA

• KNX power supply with integrated choke
• Two integrated power supplies for redundancy
• Mains voltage 230VAC (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

           - Mains voltage failure/return

           - All events are stored with time stamp in a ring buffer

           - Read out of the ring buffer by 14Byte telegram

           - Safety functions to detect a failed device in the KNX line

• 3 years warranty
