FURSE_Lightning signal devices ESP_ESP CATV/F
Product No：Pro2009414231325
Product Model：ESP CATV/F
UpdateTime：2010.06.02
Views：1493
Suitable for CATV systems using F connector coaxial cable. For frequencies between 5MHz and 1GHz. Suitable for power sources of up to 140V AC peak.
For coaxial (or twisted pair) CCTV lines use the ESP CCTV models. For coaxial RF lines use the ESP RF models. Transients can also be conducted into CATV systems via the mains power supplies. For mains power protectors see the high current or low current models.
Application
Use to protect CATV consumer installations.
Features and benefits
Restricts let-through voltage to below the damage levels of interface circuitry.
Provides repeated protection in lightning intense environments.
Low attenuation and high return loss over a wide range of frequencies ensure the protectors do not impair system performance.
Carries AC or DC power.
Substantial earth termination.
Supplied ready for flat mounting.
Strong metal housing.
ESP CATV/F installed in a basement or garage near where the coaxial cable enters the building.
Installation
Connect in series with the coaxial cable either near where it enters or leaves the building or close to the system s earth star point (to enable a good connection to earth).
