Ilevia Offers KNX Power Supply

The Ilevia A00-PS640KNX power supply produces and monitors KNX system voltage. The bus line is decoupled from the power supply with the integrated choke.

The power supply is connected to the bus line with a bus connection terminal. A reset is triggered by pressing the reset push button – the bus line is disconnected from the power supply and the devices connected to this bus line are returned to their initial state.

A 30V DC auxiliary voltage is made available via an additional connection terminal. This voltage can be used to supply a further bus line (in connection with a separate choke).


  • Provide sustainable power to other KNX equipments of the same line
  • Short circuit protection to other devices installed on the KNX line
  • Protect other KNX devices by stabilising input voltage and current
