video ground loop isolator transformer

HT7000GLIB Video Ground Loop Isolator could reduce "Ground Loop Interference" with CCTV signals and can easily install in a new or added to existing systems. It is useful where a video signal is transmitted via cable between points with different ground potentials, differences in ground potentials are typically caused by unbalanced power line loads.

Certificates of CE,FCC,RoHS passed.
