VB-1RR - Overview

Composite Video Isolator - 1ch

The Iso-Max VB-1RR is a single-channel 75 Ω video isolator for composite (baseband) video that is used to prevent 60 cycle `hum bars' even where ground voltage differences are very large such as in surveillance video systems, night clubs, video walls, broadcast stations, and industrial plants.

The Iso-Max VB-1RR is a single-channel 75 Ω video isolator for composite (baseband) video that is used to prevent 60 cycle `hum bars' even where ground voltage differences are very large such as in surveillance video systems, night clubs, video walls, broadcast stations, and industrial plants.

Designed for use with standard RG59 type coaxial cable, the VB-1RR combines true 75 Ω RCA connectors with a custom wound transformer to minimize reflection. The unique design delivers an exceptionally linear bandwidth from 10 Hz to 10 MHz with virtually zero insertion loss. Plug and play easy to use, the VB-1RR features a flanged, electrically isolated housing that is easily mounted on standard 19" rack rails or inside a NEMA enclosure. One simply connects the passive device in series and problems such as ground loops are eliminated, reducing noise by as much as 120 dB.
