Adding A/V input to hot chassis SS B&W TV

[kf4rca]

I remember years ago at a station, that we had a Panasonic monitor that had a video transformer in the video input. It took the external video input BNC connector and isolated it from the hot ground chassis. I didn't think that was too unusual and there must be other manufacturers using that idea if Panasonic was using it. The video quality was good. It was a Pro-line monitor. They trashed the monitor when we moved the station and I regret I didn't pull the circuit board. I've never seen that in a monitor since.

Hi to all,
Hi KF4RCA,

This device made by Kramer is a passive transformer video isolator similar to the Panasonic Broadcast device you mention in your post.
See Spec sheet enclosed.
It passes 5.8MHz bandpass (at -3dB), but the all-important tolerable Max AC & DC isolation voltage is not in the specs.

Could you trust it with 120VAC or 240VAC differential voltage to Gnd from a hot chassis?
enquire from the manufacturer.
