Communication technology

Lightning strikes, transient overvoltages and arc faults present a risk to sensitive systems and components in communications technology. In today’s competitive environment, system failure is a serious threat.

Reduce cost-intensive operational disturbances in safety technology and mobile radio systems. With a comprehensive protection concept to combat lightning effects, overvoltage and arc faults, you can optimise the availability of your systems and, at the same time, protect your staff and the environment.

Ensuring network availability and reliability

Reliable protection against lightning and surge damage is an important aspect when redesigning and extending the existing network infrastructure.

Transmission capacities and network availability are the most important factors. To meet the ever growing demand, existing structures must be constantly extended. New transmission technologies require constant adaptation of the hardware. Since technology is becoming ever more powerful it gets more and more sensitive.

Don't run the risk of a standstill - Rely on a comprehensive protection system

Top priority is to prevent lightning damage to the host building, mobile radio infrastructure and electrical systems. Permanent system availability is always paramount.

According to IEC 62305 the standard-compliant protection system for all components of the transmitting system consists of

External lightning protection including air-termination systems, down conductors and the earth-termination system
Internal lightning protection including surge protection for lightning equipotential bonding

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.

DEHNsecure DSE M 1 60 FM

Modular and coordinated single-pole lightning current arrester for protecting the power supply in d.c. applications. Mains follow currents are already prevented as they develop.

DEHNsecure DSE M 2P 60 FM

Modular and coordinated two-pole lightning current arrester for protecting the mast and antenna in d.c. applications. Mains follow currents are already prevented as they develop.

Safety and security systems

Ensure reliable operation of your safety systems

Be it fire protection, burglary protection or emergency and escape route lighting: Electrical safety systems are only safe if they do not fail during thunderstorms which are most common in the summer months. If lightning strikes and surges destroy safety systems and safety-related functions are thus no longer available, human life is at risk. Surges may lead to false alarms and high follow-up costs. Therefore it is vital to integrate safety systems in a lightning and surge protection concept. To this end, manufacturers, consultants and installers must comply with legal and normative requirements.

No compromises on safety

Over 100 years of experience make DEHN an acknowledged expert in the field of lightning and surge protection. Our top-quality products were approved by leading manufacturers of hazard alarm systems. Arresters which are used, for example, in fire, burglar alarm and CCTV systems were extensively tested in our in-house test laboratory. Our tried and tested lightning and surge protection as well as earthing and equipotential bonding concepts are developed by DEHN experts. DEHN products are VdS-certified and provide a high degree of quality which is continuously improved.
