Protect DC mobile communication systems

Modern mobile radio sites today rely on remote radio units and active antenna arrays. Active RF technology is installed directly onto the mast. However, being directly on the mast has a high risk of being struck by lightning. This means that protective measures against the effects of lightning and surges are particularly important here.

See for yourself. We offer you a comprehensive, useful, harmonised, complete range of products for the protection of DC systems, enabling you to plan, purchase, install and service efficiently.

Reduce the risk of coupling

The laying of supply lines in parallel with the mast poses a risk of surges being coupled. In order to limit these couplings to a harmless level, the DC lines at the base station outlet and directly at the active radio technology are connected with suitable lightning and surge protective devices.

DEHNsecure modular specially for 48 V DC

This modularly structured arrester is specially designed and tested for the high operating currents of the 48‑V DC supply.

The vibration-resistant module-locking system ensures a reliable hold between the base part and the protection module. It withstands shocks and vibrations as well as the enormous mechanical stresses during discharge.

Quick and easy installation

The replacement of protection modules is performed easily, without tools using the module release button. This means the module is replaced without interrupting the power supply unit during ongoing operations.

Overvoltage protection box – (OVP box)

Weather-resistant installation of a DEHNsecure lightning current arrester to protect active components (e.g. remote radio units, active antenna arrays or radio relay systems). The OVP box is configured to your specific application. If you are interested, please contact us.
