We design and manufacture lightning and surge protection solutions for all types of communication interfaces.

Added reliability for mission critical equipment.

Lightning storms, static discharge, secondary effects of power surges and transient ground potential energies constantly bombard your sensitive communications equipment. Zap-Tech transient voltage surge suppression (TVSS) acts as a significant measure to prevent electrical damage to your system. it also extends the life of sensitive circuits at the component level while improving system reliability. Zap-Tech offers surge protection solutions for all connector types and for any type of system.

Experience counts.

Zap-Tech corporation has over 25 years of experience in designing surge protection. We provide the most complete selection of lightning surge protection, overvoltage and TVSS products in the industry.
