For more than 100 years DEHN has been serving the electrical industry. From the beginning, protecting buildings and personnel from the effects of direct lightning strikes, to its current business of protecting electrical equipment and systems from the consequences of lightning currents and voltage surges.
As electrical power systems became more complex, the electrical loads, such as process control, computer and telecommunication systems, solid state controllers and relays become more commonplace and sensitive to the aberrations that appear on these power sources, DEHN has continued to improve and develop new products and technologies for maintaining the integrity and reliability of these modern systems. This has lead to DEHN’s leadership role in MOV based TVSS technology and their capability to suppress even lightning rated transients with 10/350 µsec durations.
DEHN currently employs a staff of more than 600 engineers, technicians, craftsman and administrative personnel, and has contracting branches employing another 250 employees, serving in subsidiaries and with partnering companies in more than 50 countries throughout the world including, DEHN Inc. serving the United States market. DEHN heavily invests in its own research and development, as well as contributing and exchanging information with others at international technical conferences and serving on technical Standards committees, to further the knowledge and technology in the fields of lightning protection and transient voltage surge suppression. DEHN manufactures its component products under an ISO 9001 certified Quality System.
DEHN manufactures a full range of Lightning and Surge protection (TVSS) for application on Instrumentation, Measurement and Control and 600 Volt class power systems. Products are configured for various applications including DIN rail mounting for two wire, Ethernet, RS232, coaxial (for RF and video), NPT pipe enclosed assemblies, as well as complete TVSS units built into NEMA rated enclosures for power applications
DEHN devices are rated for 600 Volt class applications and are respectively rated for Protection Categories (per ANSI C62.41-1991) C, B, or A., are compliant to UL 11449 3rd Edition and components have been tested and approved to conform to international standards as stated, and as indicated also bear UL and CE designations.
