These analogue video isolators are useful in both broadcast and CCTV applications, where there are differences in earth potential between video circuits, such as between different locations on a site, which can cause disturbance to the video signal with the introduction of supply frequency noise or 'hum' and, at worst, can be a safety issue.
A special transformer is used with very wide band-width performance, and a capacitor in series with the input prevents saturation that might be caused by a DC component in the signal.
They are a portable design, housed in a standard Canford extruded box with protective ABS bezels, for life in the tool-kit ready for trouble-shooting. Alternatively they may be fixed to a flat surface using an Extruded-box mounting kit, stock code 16-722.
Single and dual channel versions are available, with BNC input and output connectors.

Whilst the transformer is capable of broadcast-class performance, by it's very nature it blocks the DC part of the luminance information, which has negligible effect on picture quality in most circumstances.
