SEL SP-44 - active protection system for electric circuit and ground
DESCRIPTION
Awards
The device is a technical mean for active information protection for the top-secret category objects.
SEL SP-44 prevents information leakage through the powersupply and ground lines providing a masking noise there in the frequency range of 0.01 - 400 MHz. It also suppresses wiretaps which are using these lines as a data-transmitting channel.
Advantages:
• Doesn’t influence PC performance and consumer electronics functioning.
• Two independent uncorrelated noise generators for the low and high frequency bands for the circuits "phase" - "earth" and "zero" - "earth" allows to eliminate the possibility of informative signal
interception for the anti-phase and in-phase connection schemes.
• During operation the unit constantly performs a self-test, and in case of failure gives sound and light signal.
