Description
DLA protects information and communication technology, telecommunication equipment and data technology systems from lightning effects and surges.
The electrical circuit of the DLA consists of a combination of high-performance gas discharge tubes and fast-switching diodes for high discharge capacity and fast response behaviour.
The shield connection is additionally earthed via a gas discharge tube. The earthing connection is conveniently made via the top-hat rail. When the plug-in module is unplugged, the transmission signal is not interrupted.
