Description

The MDT KNX Power Supply with integrated choke supplies the KNX Bus with a constant, stabilized 30 V DC voltage. The redundant Bus Power Supply has two integrated power supplies to increase operation reliability. If one mains voltage or one of the internal power supplies fails, the KNX bus voltage maintains its stability by the second power supply. The integrated bus coupling unit with diagnostic function monitors the bus voltage, bus current, bus overload and bus voltage failure / return. All events are stored with time stamp in the internal ring buffer. The ring buffer can be read out by a 14 Byte telegram.

• Supply Voltage: 640mA
• Diagnostic Function: Yes
• Redundant: Yes
