System Devices

Power Supply 320 mA

The 320 mA voltage supply generates and monitors the KNX system voltage, via the BUS output, it supplies a bus line with max. 32 instabus users without any additional KNX reactor. The 30 V DC output is without reactance and makes possible the supply of a further line (e.g., main line) by means of a separate KNX reactor, to be installed separately, as well as a line coupler.
Alternatively, this output can be used for the supply of further functional devices (e.g., auxiliary voltage for binary inputs). The load can be distributed to the outputs as desired; the total nominal current must not be exceeded, however. The mounting of the REG is done on a 35 mm mounting rail.

  • Connection of the bus lines via KNX terminals, no data bus required
  • Switch for resetting the bus line
  • Colored LED for displaying operation, overload, overvoltage and reset
