Optical video isolator cab-3
* Output, fully isolated from input
* High linear transmission of video signal
* Wide band of video signal s gain till 10 MHz
* Fixed sync tip clamp of video signal
* Built in power supply source
High quality insulating opto decoupled video amplifier CAB-3 is intended for providing full isolation between sources of video signal and receiving gear for video signal, such as monitors, projectors, digital displays. CAB-3 allows to eliminate such well-known problems of installers of video monitoring systems, as background interferences from ground current loops , to prevent passage of dangerous constant current and other interferences, which degrade quality of signal transmitted by video lines.
CAB-3 as active opto insulating device has high linearity and wide band of passing video signal in comparison with devices with insulating transformers.
* Insulating opto decoupled video amplifier CAB-3 has coaxial 75 ohm BNC input connector which is isolated from BNC output connector with help of optoelectronic transducer on microcircuit of Hewlett Packard firm with dielectric breakdown voltage > 3000 V. In device s output part there are made regulation of video signal amplification and fixed lock-on of its level, and controlled correction of video signal made on microcircuits of JSC RD ALFA md .
* Amplifier CAB-3 has built in power-unit for ac power supply 220 V.
* Amplifier is intended for work indoors (category IP50), is notable for small power consumption, reliability, simplicity of operation.

* Noise & Cross Talk Immunity
* High quality transmission of symmetric video signal overy twisted pair wires at long distances from 200 to 2000 meters. Exceptional noise cancellation and cross talk immunity. Video quality is assured even when signals are used in electrical noisy environment.
* Easy Installation, Simple Adjustment
* All devices have the unique switcher for compensation of line s length and one variable resistor for gain control.
* All devices have special circuit design for sync tip clamp option for video signals.
* All devices have special power unit, which provides the big dynamic range of video signals.
* The built in power unit is with electronic protection.
* Protection from Dangerous Voltage
* There is protection of valuable video equipment by suppressing external dangerous voltage. Virtually all products offer line-to-line (Differential) and line-to-ground (Common) protection from dangerous voltage. (See table of absolute maximal operating voltage).
* Devices are enclosed inside the case with dust and moisture protection.
