BLITZDUCTOR ® XTU<br />
Universal lightning current / surge arrester<br />
BLITZDUCTOR XTU for protecting different balanced signal and data<br />
interfaces. Space-saving two-part design with base part and protection<br />
module for DIN rail mounting.<br />
The compact BLITZDUCTOR XTU combined lightning current and surge<br />
arrester is designed for protecting information and automation equipment<br />
and systems. Due to its unique actiVsense technology, the nominal<br />
voltage is not specified. This allows the arrester to be used for voltages<br />
ranging from 0 to 180 V with a ± 5 V/50 MHz signal voltage. The nominal<br />
current is limited to 100 mA which is completely sufficient for information<br />
technology systems.<br />
Its innovative actiVsense technology allows the arrester to detect the signal<br />
voltage and to automatically adapt its voltage protection level to this<br />
voltage. This makes the arrester ideal for applications where changing or<br />
slowly fluctuating signal levels (≤ 400 Hz) are to be expected. In case of<br />
interference, BLITZDUCTOR XTU arresters have an adapted minimal<br />
residual voltage for every signal voltage, thus providing maximum protection<br />
for devices and system circuits connected to them.<br />
BLITZDUCTOR XTU is available in two versions. The four-pole version provides<br />
protection for two separate balanced interfaces, that is the arrester<br />
automatically detects the operating / signal voltage for every pair and<br />
optimally adapts the voltage protection level for every signal circuit. This<br />
allows to protect two different balanced interfaces by means of a single<br />
arrester, thus reducing installation time, saving costs and reducing the<br />
number of arresters to be used. If only one signal interface is to be protected,<br />
a two-pole version can be used for a balanced data interface (one<br />
pair). This version also allows direct or indirect connection of line shields<br />
to the equipotential bonding.<br />
The DIN rail mounted arresters are ideally suited for use in information<br />
technology transmission systems such as telecommunication, bus or<br />
measuring and control systems.<br />
Optimally adapted voltage protection<br />
level with integrated actiV -<br />
sense technology for the protection<br />
of terminal equipment<br />
To ensure a high availability of<br />
signal circuits, the integrated<br />
LifeCheck function allows to<br />
quickly check whether arresters<br />
are previously damaged<br />
The protection module of the<br />
pluggable arrester safely snaps<br />
into the base part, thus ensuring<br />
shock and vibration resistance<br />
