Radio base station - a.c. power supply

Protection of the radio base station

The radio base station is typically supplied by a separate line – irrespective of the rest of the building. The supply line to the cell site downstream of the meter and in the a.c. sub-distribution board upstream of the radio base station should be protected by adequate lightning current and surge arresters. This is required by the guidelines of all network operators, the German “ABB bulletin No. 16” as well as DIN VDE 0800-300 or IEC 62305.

New space-saving design!

Total performance packed into just 4 standard DIN modules! DEHNvap with its new compact design has a total current of 100 kA (10/350 µs) making it the smallest combined arrester with these performance parameters currently available on the market.

This device fulfils the maximum requirements on lightning current discharge capacity according to IEC EN 60364-5-53 and the requirements of IEC EN 62305 with regard to class of LPS I/II.

Simple realisation of feed-through wiring is possible by connecting in series, e.g. with STAK 25.

Preventing false tripping of system fuses

The infrastructure in main and system power supplies is protected by proven combined arresters (combined lightning current and surge arresters). DEHN combined arresters are characterised by an extremely high follow current extinguishing and limitation capability, thus preventing false tripping of system fuses which would disconnect the cell sites. This leads to an extremely high system availability.

Universal usage – irrespective of the power system

DEHNvap CSP was specifically designed for the requirements in the mobile radio sector. This arrester can be used universally irrespective of the power system. Thanks to its integrated 3+1 circuit, it reliably protects TN-S and TT systems.
