STC-1280.01 Power supply 1280mA with diagnostic function

Type: MDT STC-1280.01 Power supply 1280mA with diagnostic function

EAN: 4251916100025

Bus System: KNX (TP)

Degree of protection: IP20

Mounting: DIN rail

The MDT KNX bus power supply with integrated choke supplies the KNX/EIB bus with a constant, stabilized DC voltage of 30 V DC. The integrated bus coupler with diagnostic function monitors bus voltage, bus current, bus overload, mains voltage failure and mains voltage recovery. All events are stored in the internal memory with a timestamp. The memory can be read via a 14-byte telegram.

The current operating status is indicated by 8 coloured LEDs at the top of the device:
- RUN (green LED): normal operation
- I>Imax (red LED): overcurrent
- Reset (red LED): reset process is active
- Temperature alarm (red LED): excessive temperature
- Operation > 60% (red LED): KNX bus overload
- Bus error (red LED): bus errors, telegram collisions and unacknowledged telegrams
- Missing device (red LED): missing KNX device
- Program (red LED): programming mode

All devices are overload resistant and also have an output without a choke.
