Top-Level Security with Dehn

Be safe against lightning and overvoltages

The increasing role of electronic devices in systems in line with developing technological needs and the increase in stormy weather events due to changing climate conditions increase the risks that sensitive automation and communication systems will be exposed to every passing day.

DEHN offers complete solutions from a single source for all your needs in lightning and overvoltage protection. It offers the right products and technical services for planning, technical consultancy, risk analyses and application needs.

Dehn, a family company based in Germany, maintains and develops its position as a leader and a pioneer company that sets standards in its sector with the experience it has gained in lightning and overvoltage protection systems, which it has focused on for over a century.

Included in its product portfolio;

External lightning systems: Provides protection against the physical effects of lightning with the Faraday Cage method, which is the correct protection method included in the IEC 62305 standard. Provides solutions from a single source for all needs with capturing ends, lowering conductors, grounding equipment, insulated cables and accessories for these products.

Internal lightning systems: A lightning strike that is safely transferred to the ground with an external lightning system causes a change in the ground potential. As a result, unwanted current flows may occur that may damage sensitive electronic equipment. These situations may also be produced by other sources that can produce surge current within the system. In order to protect against these risks and to have a sustainable operation, precautions should be taken with surge arresters, which are internal lightning systems. Dehn protects your system against risks with its wide product family for different needs, from supply lines to communication and data applications, from analog signals to data lines.

DEHN protects photovoltaic systems

DEHNkombo YPV

Protect your PV system from lightning and surge damage
DEHNcombo YPV – a varistor-based type 1 + type 2 combined arrester – protects the DC side of the inverter, combiner box or PV modules.

Particularly interesting: This arrester is universally applicable, meaning that it can be used for applications ranging from small rooftop to multi-megawatt systems.

Protection concept for rooftop and free field systems

Rooftop and free field systems should be protected from direct lightning strikes and transient overvoltages with the help of a comprehensive protection concept consisting of external and internal lightning protection.

DEHNcombo YPV is suitable for earthed (earthing of DC+ or DC-) and floating systems and can be used up to 10 kA without additional backup fuse. The arrester is available for system voltages UCPV ≤ 1200 V and ≤ 1500 V, thus ensuring effective protection of terminal devices.
