MDT 1280mA Diagnostic Power Supply with Additional 30V DC Output

The MDT 1280mA KNX power supply with integrated choke provides a stable 30V DC for the KNX bus and includes an additional output without choke for extra applications. This power supply offers continuous diagnostics of bus voltage, current, overload, and any bus faults. Events such as voltage failure or return are logged with a timestamp in an internal ring buffer, which can be read via a 14-byte telegram. The device provides high reliability and can automatically detect faulty devices in the KNX line.

Main Features:

Nominal current: 1280mA (choke output)
Additional output without choke: 30V DC for additional load
Diagnostic function: Continuous monitoring of bus voltage, current, overload, and bus faults
Ring buffer: Stores all events with timestamps
Bus fault detection: Detects missing devices in the KNX line
Programmable functions: Via ETS software (ETS 4/5)
LED indicators: 8 colored LEDs display status, including normal operation, overload, bus faults, and programming mode
