System Devices

Power Supply 640 mA

The KNX voltage supply generates and monitors
the KNX system voltage by means of the integrated reactor. The bus line is decoupled from the KNX voltage supply. The connection to KNX is made with a bus terminal. When the reset button is pressed, a reset is triggered for 20 seconds(regardless of how long the button remains
pressed). The bus line is enabled and the bus users connected to this bus line are reset to the basic status. If a longer reset is needed, the bus terminal must be disconnected from the supply voltage. A 30 V DC auxiliary voltage output is provided by an additional terminal.

  • 30 V DC
  • DIN rail fixing
  • 640 mA current
  • Integrated choke
  • Switch for resetting the bus line
  • Powers up to 64 EIB/KNX devices
