Active protection system for electric circuit and ground SEL SP-44

	The device is a technical mean of active protection of information. The SEL SP-44 prevents from information leakage through the power-supply and ground lines providing a masking noise there. It also suppresses wiretaps which are using these lines as a data-transmitting channel.

Technical characteristics:
Noise frequency range	0.01 – 300 MHz
Lines protected	power supply, ground
Spectral-noise density (at 50 Ohm load relatively 1 µV/ √ kHz) in the frequency bands, not less than:
0.01 – 1 MHz	90 dB
1 – 10 MHz	70 dB
10 – 100 MHz	50 dB
100 – 300 MHz	35 dB
Noise level adjustment range in the frequency bands, not less than:
0.01 – 0.5 MHz	20 dB
5 – 300 MHz	12 dB
Quantity of independent noise signal channels	2 for phase-to-ground and zero-to-ground circuits
Noise quality factor	not less than 0,9
Leakage current through ground line	not more than 1 mA
Noise actuation control	manual, remote, RS-485
Operation conditions:
operating temperature range	from 0 up to+50 °C
relative humidity at + 25 °C	up to 85%
atmospheric pressure	750 ± 40 mm Hg
Power supply:
AC mains	220 V ± 10% 50 Hz
power consumption	not more than 12 W
Mass-volume:
dimensions	172 х 172 х 42 mm
weight	not more than 1.5 kg
