The compact arresters of the DEHNbox product family are combined lightning current and surge arresters designed for protecting information, measuring and control and automation equipment and systems. 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 DEHNbox TC 180 and DBX U4 KT BD S 0-180 to be used in harsh environments such as in moist atmospheres. The cable entries are designed as installation-friendly self-sealing rubber grommets. These grommets allow easy and fast installation and prevent the ingress of moisture and dust. Both the cores and an installed line shield can be contacted via spring-loaded terminals without the need for screws. DEHNbox is available in three versions:
DEHNbox TC B 180
DEHNbox TC B 180 has been specifically developed to meet the latest requirements of telecommunication applications such as VDSL2 vectoring and G.fast (up to 1 Gbit). The main focus of this surge arrester is, in addition to optimum protection of the terminal equipment, on low-attenuation signal transmission and simple handling. Due to the special snap-in cover of the IP 20 enclosure, several arresters can be locked together and screwed to the wall. The telephone line is mounted at the input without tools via push-in terminals. On the output side, the connecting line can be connected to push-in terminals or an RJ45 socket, depending on the application (mounting near the network termination or directly on the router). It is also possible to earth the cable shield directly or indirectly. With a maximum continuous operating voltage of 180 V d.c. and a maximum operating current of 1 A, the DBX TC B 180 can also be universally used in non-telecommunications applications to protect measuring and control interfaces and other applications.
DEHNbox TC 180
The arrester is optimised for use at telecommunication connections and devices such as analogue telephones as well as ISDN and VDSL2 connections. With a cut-off frequency of 250 MHz, the arrester is also capable of transmitting high-frequency signal parts and can thus be used at high-performance signal interfaces. As an alternative, DEHNbox TC 180 can also be installed at measuring and control interfaces up to a voltage of 180 V and a maximum current of 750 mA.
DEHNbox TC 180 enables the fast connection of one pair without tools and makes it possible to use cable ties to fix the connection cable to the printed circuit board (strain relief). The connection space in the box and the position of the terminals ensure optimal conductor routing and easy conductor connection.
DEHNbox with actiVsense technology
This arrester type does not have a specific nominal voltage and can thus be used for voltages ranging from 0 to 180 V with a superimposed signal voltage (± 5 V/50 MHz). The nominal current is limited to 100 mA which is sufficient for information technology systems. This innovative actiVsense technology allows the arrester to detect the signal voltage applied and to automatically adapt the 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 voltage protection level for every signal voltage, thus providing maximum protection for the devices and system circuits connected to them. The four-pole version of DEHNbox provides protection for two different balanced interfaces, e.g. a bus interface with a system voltage of 5 V and an analogue measured value signal with a system voltage of 24 V. The arrester is ideally suited for domestic and industrial use in information technology transmission systems such as telecommunication, bus and measuring and control systems.
