High-voltage transients (power surges) caused by lightning or other electrical disturbances have the ability to cause serious damage to equipment and valuable data. Telebyte's line of Lightning/Surge Protectors includes products designed to accommodate these transients, slow them down and redirect them to a low impedance path-to-earth ground. Check out our Lightning Sponges for line drivers/modems and telephone lines, Ethernet surge suppression cards and more! Interfaces for RS-232, RS-422, and RS-485.
