SP-44 for protection of 220 volts mains
The generator is a technical means of active informational protection of the top-secret category objects that provides protection of intercom systems and data transmitting systems that use single-phase 220V with ground net as an information transmitting channel from any type of interception devices by means of producing wide-range noise.
Distinctive features: does not interfere with radio reception and does not influence PC performance and consumer electronics functioning; is not sensitive to peaks of net voltage up to 1kV.
