M17108 Izolator galvanic cu protecție fulger HSO-1F EXT (BNC)
HSO-1F EXT is a galvanic isolator for use in 75 Ω coaxial line, combining very efficient surge/overvoltage protection of the connected devices. The device is specially dedicated for CCTV systems transmitting HD video signals (AHD, HD-CVI, HD-TVI), as well as can be used in CVBS systems.
It galvanically isolates two parts of the transmission path, such as the part with a camera and that with a DVR or monitor, protecting the devices against the effects of potential differences (image distortions caused by stray currents). The application of the isolators is recommended in CCTV systems located in industrial environments, such as metal halls, on metal poles, and in the case of power supply from different segments of AC power network. In such circumstances some differences in potential appearing between individual grounding points introduce unfavorable operating conditions of the input/output circuitry. The differences and stray currents can generate disturbances visible in the picture and even damage the connected devices.
Maximum level of protective effectiveness is provided by galvanic isolation up to 800 VDC and 2 x 10 kA surge protection, containing a unique solution with ultra-fast MOSFET fuse. It ensures extreme immunity against voltage surges, atmospheric discharges and potential differences. The MOSFET fuse increases the effectiveness of surge protection and protects the transformer of the isolator from damage due to the flow of large impact current pulses.46,2 RON
