16-channel surge protection for HD CCTV, compatible with HD-CVI, HD-TVI, AHD, mounted in rack cabinet LHD-16R-PRO
LHD-16R-PRO is rack mount system designed to protect CCTV instalations from lightnings, overvoltages and vandalism.
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.
The device include high quality impedance converter (video balun), change impedance between twisted pair and 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. High quality core, with linear characteristic allows signals move to 60Mhz. It allow to supports video resolution up-to 8Mpix.
LHD-16R-PRO is high quality, 16-channel surge protection for UTP and coaxial cables. The device is dedicated to CCTV high resolution, using standard signal AHD, HD-CVI, HD-TVI oraz Turbo HD. Also is compatible with analog systems PAL and NTSC.
The device used two grade protective acting in the right order while a lightning surge or other sources, both high and low. This 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 the 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 capacitance circuit (8~16pF) 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-16R-PRO can be use in systems multi channel systems with 1-channel surge protection HDO-1F-PRO, HDT-1F-PRO or multi-channels protectors . In order to ensure full protection it is recommended to use surge protection on two ends of cable with their ground.
The LHD-16R-PRO series is designed to Rack Cabinet. The patch panel may be mounted in front or at rear of rack cabinet with a LK-MOUNT brackets
