30 kV 10 mA power supply

On 9 Nov 2006 10:25:32 -0800, "Tom Bruhns" Gave us:

I have a 37" CRT display and it draws 350W. Of that 350W, I'd bet that over half of it is used somewhere other than the anode supply. Nearly 50W of it are used in the audio circuits alone (when fully driven). Usage placards don't lie.

Just so you know, I have manufactured several products using the biggest OEM flybacks available. Commercial products like 20kV oil filtering tanks, among others.

Try again.

Gee, something seems unreasonable about the several kilowatts claim, my brother's 65 inch draws less than 5 amps at 120 volts. My 27 inch TV draws less than 200 VA or watts.

Still the major power losses are in generating the deflection currents rather than in energizing the CRT. Please note the vastly lower power requirements for large screen TVs and displays that do not use CRTs.

"Liquid cooling?" Which make and model are going on about. I have seen the guts of scores of projector TV sets and high resolution displays (up to

3200 x 2400) as well; damn few even had a fan, the rest are convection cooled.

Since you didn't disagree with anything I put in the posting to which you replied (or even the preceeding one), I don't know why you'd suggest that. Perhaps you thought you read something in my posting that wasn't there.

Cheers, Tom

I should have clarified-- in every projection TV I've seen the face of the CRT has glycol liquid in front of it. The heated liquid rises to the top where there's a heatsink to convey the liquid's heat to the air.

You're too goddamned retarded to even know how to answer the right post... Yet you are calling me an idiot. Sure...

Your remark was more than a bit ambiguous "more than that from the mains..."

More than what? I assumed you meant the 350W number. If so, your assertion was incorrect. Granted the largest of the CRT family out there does draw more than 350W, but I used my 37" as a good example.
