LCN · Buffer amplifier

For DIN rail mounting


The buffer amplifier allows the separation of data lines and prevents accidental energisation in distribution networks.

It prevents the triggering of an RCD due to data current. In large systems, many thousands of metres of lines can be generated with the buffer amplifier.

In distribution networks with several RCDs, each RCD must be equipped with its own buffer amplifier in order to separate the data line. The buffer amplifiers are connected to each other via a 2-core shielded line, whereby no more than a total of 15 buffer amplifiers can be connected. If buffer amplifiers are used in several distribution networks, the connection of the nodes is effected by means of segment couplers (LCN-LLG or LCN-LLK).

BEGA AR

BEGA AR is pleased to help you assess our luminaires in your own private setting. In a virtual presentation you can place up to five different luminaires simultaneously in any positions you like: in the house, around the house or in the garden. You can then view them from all angles, switching them on and off and even taking photos ofthe various scenes.

Electrical safety

The luminaires in this catalogue are designed and produced on the basis of the EN 60598/VDE 0711 standards. The majority of the luminaires bear the relevant test mark on the type plate as well as on the packaging and instructions for use. The other luminaires have been or will be submitted for certification, but the certification and approval procedure is still in progress. We can provide information on the status of the certification procedure at any time. Special orders are produced in accordance with the above set of regulations.
