220 V mains protection

SEL SP-44 - active protection system for electric circuit and ground
	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. Noise frequency range 0.01 - 300 MHz Lines protected power supply (220 V), ground

Antiinterference supply-line filter FSP-1F-7A

The filter is intended for protection against information leakage through power-supply lines 220 V. It is used for electromagnetic power-supply decoupling of electronic equipment from electrical network .

Distinctive features:
-protection of office equipment against external HF interference;
-provides a raise of interference immunity of electronic devices.

working frequency range 0.15-1000 MHz
admissible load current 7 A
