DEHN’s Blitzductor XTU modules are combined lightning current and surge arrestors for protecting information and automation systems. The nominal voltage is not specified, allowing the arrestor to be used for all voltages in the range of 0-180 V d.c.
The device’s actiVsense technology allows it to automatically detect the signal voltage of the information signal and adapt its protection performance to this voltage. Moreover, it continuously adapts its voltage protection level to the currently applied signal voltage and is thus suitable for all applications where changing voltages occur. In case of interference, Blitzductor XTU arrestors always have an adapted, minimal residual voltage for every signal voltage.
The arrestors also feature a patented LifeCheck monitoring function which allows for easy testing of arrestors during operation, provided that the protection module is plugged in. This monitoring function also allows the arrestor to operate even if it is pre-damaged by overload, thus ensuring safe operation.
Blitzductor XTU arrestors are also ideally suited for retrofitting existing systems with surge protection devices or replacing existing arrestors. They are pluggable, consisting of a BXTU protection module, which contains all surge protection components, and a DIN rail mountable BXT base part.
