Power supplies for supplying KNX devices with bus voltage.

Features

Features

  • Output with integrated choke to supply KNX bus lines.
  • Output DC 30 V to supply additional devices.
  • Rated current can be flexibly split up amongst outputs.
  • Reset button.
  • Short-circuit-proof.
  • Overvoltage protection.
  • Open circuit-proof.
  • Suitable for operation in systems with emergency power supply.
  • Isolated signal contact for operating message and diagnostic message.
  • The uninterruptible power supply 640 mA generates the KNX system voltage.
  • With integrated choke for de-coupling the bus line from the power supply.
  • With connections for a lead-gel rechargeable accumulators for buffering KNX voltage in case of a mains failure.
  • Up to two lead-gel rechargeable accumulators can be connected and charged via the uninterruptible power supply.
  • The charging voltage is controlled depending on the temperature using a temperature sensor.
  • The uninterruptible power supply has a zero-voltage 2-way switch for reporting a fault (e.g. mains failure, battery failure, overload, or short circuit).
