The Edco FAS-TEL-DOT is a single pair telephone protector that implements an advanced three-stage hybrid design. This unit addresses over-voltage transients with gas discharge tubes (GDT) and silicon breakover devices.
The Edco CAT6-POE Series is designed to work on Category 6 Power-Over-Ethernet transmission line applications.
Provides isolated power loop circuit protection in applications where higher current is required, such as fire alarm and security systems. Non-degrading SADS will last the lifetime of equipment, ensuring uptime.
Suppressor specifically designed to protect electronic instruments used by the water/wastewater industries.
The Edco SLCP Series are four-wire modules designed to protect signaling line circuits (SLC). The device has 0 ohms of resistance and offers line to ground protection.
Employs three-stage hybrid technology to address overvoltage transients and sneak and fault current for phones, data/communication lines and transmitters.
Designed to protect two pairs of wires specifically for alarm and security systems where operating currents can be as high as 5 Amps.
Four-pair telephone/data line protectors that implement advanced two stage hybrid design. These units address over voltage transients with silicon breakover devices, while sneak and fault currents are mitigated with PTC technology, which consists of solid state resettable fuses.
Specifically designed for lightning protection on closed circuit TV systems.
This product is designed to protect coaxial cable TV signal lines from lightning transients.
