Surface-Mounted SPDs • Combined lightning current and surge arrester – Capable of carrying lightning currents up to 10 kA (10/350 μs) – Low voltage protection level, also suited for the protection of terminal equipment – For installation in conformity with the lightning protection zones concept at the boundaries from 0 A – 2 and higher • actiVsense technology – Automatically detects the signal voltage from 0 to 180 V – Optimally adapts the voltage protection level to the currently applied signal – Adapted voltage protection level allows terminal equipment to be protected DEHNbox Universal lightning current / surge arrester • Universal use – One arrester type for two different signal circuits – Suitable for wall mounting, degree of protection IP 65 – Easy retrofitting DEHNbox used for a telecommunication connection (example: U k0 interface) The compact DEHNbox combined lightning current and surge arrester is designed for protecting information and automation equipment and systems. Due to its new actiVsense technology, the nominal voltage is not specified. This allows the arrester to be used for voltages ranging from 0 to 180 V with a ± 5 V/50 MHz signal voltage. The nominal current is limited to 100 mA which is completely sufficient for information technology systems. Its innovative actiVsense technology allows the arrester to detect the signal voltage and to automatically adapt its voltage protection level to this voltage. This makes the arrester ideal for applications where changing or slowly fluctuating signal levels (≤ 400 Hz) are to be expected. In case of interference, DEHNbox arresters have an adapted minimal residual voltage for every signal voltage to provide maximum protection for devices and system circuits connected to them. DEHNbox is available in two versions. The four-pole version provides protection for two separate balanced interfaces, that is the arrester automatically detects the operating / signal voltage for every pair and optimally adapts the voltage protection level for every signal circuit. This allows to protect two different balanced interfaces by means of a single arrester, thus reducing installation time, saving costs and reducing the number of arresters to be used. If only one signal interface is to be protected, a two-pole version can be used for a balanced data interface (one pair). With its surface-mounted plastic enclosure with integrated fixing lugs, DEHNbox is ideally suited for wall mounting and can be easily retrofitted into existing equipment and systems. The IP 65 degree of protection allows the arresters to be used in harsh environments such as in moist environments. Cables are therefore entered via easy-to-install self-sealing rubber membranes. These membranes allow easy and fast installation and prevent the ingress of moisture and dust. Both the line wires and an installed line shield can be contacted by means of spring-loaded terminals without the use of screws. Two separate terminals allow a line shield to be directly or indirectly connected to the equipotential bonding system. The arresters are ideally suited for domestic and industrial use in information technology transmission systems such as telecommunication, bus and measuring and control systems. 250 V Up 200 V 150 V 100 V 50 V 0 V C2 C3 UN U p line-line for In (8/20 μs) C2 U p line-line for 1 kV/μs C3 U N 20 V 40 V 60 V 80 V 100 V 120 V 140 V 160 V 180 V Self-sealing rubber membranes Spring-loaded terminals allow lines to be connected without screws Fixing lugs on the enclosure for wall mounting Operating voltage U N Voltage protection level diagram DEHNbox www.dehn.de 263
