The device of protection against the pulse retension (UZIP) NZC of the EZETEK trademark is intended for protection of chains of data transmission, alarm chains, etc. against storm and switching retension.

It contains two steps of protection: the first is executed on the basis of powerful gas rated sportsmen (GDT), the second ― on the basis of high-speed protective diodes. Protection of the scheme against retension is provided on chains the line earth and the line line.

Advantage of this device before analogs is the reduced parasitic capacity that allows to transmit a signal with a frequency up to 30 MHz without attenuation.

Feature of this UZIP is existence of a thermal contact which switches the line to the earth at a device overheat: for example at short circuit of a chain of power supply on alarm chains.

The design of UZIP has width reduced in comparison with analogs.
