DEHN schützt Mobilfunk - DC Lösungen
Remote Radio Unit Technologies - d.c. power supply

New technologies require special protection

Modern mobile radio technologies include remote radio technology where the HF amplifiers are installed in a separate housing next to the antennas.

 

Risk of injection

If supply lines are installed in parallel to the mast, there is the risk that surges are injected into these lines. The same applies to the antenna lines. To reduce injection of surges to an acceptable level, the supply line leaving the base station and the supply line at the amplifier near the antenna are protected by installing adequate lightning current and surge arresters.

DEHNsecure modular particularly for 48 V d.c.

Protect your system with DEHNsecure. This modular arrester is specifically designed and tested for the high operating currents of the 48 V d.c. supply.

The vibration-resistant module locking system ensures that the protection module is firmly secured to the base part. It withstands shock, vibration and the enormous mechanical load of discharge occurrences.

Good to know: The protection module is replaced without tools by simply pressing the module release button, meaning that it can be safely replaced during operation without interrupting the power supply.

 

Protection of the Remote Radio Head
