Surge protector for video signal
This product has the advantages of fast action time,little insertion loss,accurate clamping and low output residual voltage,it can also effectively restrain overvoltage pulse inducted on the signal transmission line of a camera gun to protect a video monitoring device from damage due to overvoltage pulse.It is a new video signal protection product and it is suitably used in video monitoring devices such as the camera gun,a video distributor and a video matrix switcher.
