LHD-8R-EXT-FPS is rack mount system designed to protect CCTV instalations from lightnings, electrostatic overvoltages and vandalism and module supply power.
LHD series is universal for UTP twisted pair and coaxial cable. You can choose which one will be connected by switching jumpers on PCB (Coaxial / UTP). It’s a perfect solution for installations with different types of cables.
Built-in camera power distributor FPS - provides 8 independents power outputs, protects from short circuit and lightnings. It is equipped on optical signal of power supply to each channels and buzzer signaling of short circuit on any of them.
The device include high quality converter (transformer), change impedance UTP to coaxial cable.
The device dedicated is to transmission signal high frequency, which using to transmission Video HD in systems AHD, HD-CVI, HD-TVI / Turbo HD. Converter uses a high quality inductance of amorphous core, with linear characteristic allows signals move to 42Mhz.
The device used three degrees protective acting in the right order while a lightning surge or other sources, both high and low. While normal operation, the signal transmission circuits are not galvanically connected to ground, so are no harmful ground loops and interference, the HD signal. The protection is based on disconnection (separation) circuit by high-speed MOSFET fuse and then retrive electric charge to the ground the circuitry already in the early stages of formation, which delays the appearance of the destructive voltage on the input circuit CCTV equipment. At the time in pulse overvoltage is discharged to ground using a separate cable. The protection is based on suppression of an electrical charge to the circuitry already in initial stage of formationand delays the emergence of the destructive voltage on the input circuit CCTV equipment. At the start of the primary impulse overvoltage, he is from the earth is neutralized using a different cable to ground. Surges generated inside the wire and secondary overvoltage, are eliminated before other circuit, decoupling special resistor. This results in a high strength to impulses multiple devices (stun guns) and ensures the order in each action grade protective.
Low capacity circuit (2~4pF) has minimal effect on signal transmission from 0 ~ 100MHz, which for complex signals AHD HD-CVI and HD-TVI is very important, because it does not cause large attenuation.
LHD-8R-EXT-FPS may be use in systems multi channel with connect surge protection 1-channel series Extreme or Profesional. In order to ensure full protection. It is recommended to use surge protection on two ends wire signal along with their ground.

LHD-8R-EXT-FPS a high quality, 8-channel surge protection for wire UTP. The device is dedicated to CCTV High Definition, using standard signal AHD, HD-CVI, HD-TVI oraz Turbo HD. Extreme Series has the latest solution in the form of a superspeed automatic fuses, performed in MOSFET technology. Device are very low electrical resistance during normal operation. At the time of nominal operation is controlled intensity and increase current above 100mA, the input circuit is automatically disconnected from the output circuit in a very short time.
