DLA protect I&C, telecommunication equipment and data technology systems from lightning effects and surges. Designed for DIN rail mounting, these surge protectors can be used for all applications with voltages from 6 V to max. 170 V and transmission rates up to 10 Mbit/s and protect one (DLA) to two (DLA2) pairs with a plug-in protection module. 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. Special versions: DLAH are protective devices for applications with higher current values, operating current for connected operating devices up to 2.4 A. DLAW is a version which interrupts the signal transmission when the protection module is pulled out. D3 types aim to realize fine protection and D2 types is specific for floating applicaiton.
