25KHz 600V Shock Hazard?

sorry, a typo, should say between 20-40 KHz!

Hi

not sure about your browser but I have a "google" window top right.. I typed in "40KHz 600volts safety" and come up with a mountain of results.

Give it a go...

Really? Gosh, why didn't I think of that? The "mountain" I got was 100% irrelevant, at least through the first few hundred results. If you found anything relevant in your search, then please post that! If anyone has any useful experience with these frequencies and voltages, would like to hear about it. cheers.

One of the hard parts about this kind of research is standards are not typically free. You buy one, only to find out that it refers to another.

This is a good forum for asking questions like this, but get ready to be bombarded with comments like, dont kill yourself, if you have to ask you will kill yourself, nobody help this guy he will kill himself, and lots of critism about how your question doesnt have enough information and how you should hire a proffesional becuase electricity is dangerous. I think some of thes folks have been at this so long they get burned out and dont realize how jaded/impatient they have become.

Its my understanding that the main injuries from electricty are burns and the stopping of your heart. 2000 Watts is a lot of power no matter how you slice it. Here is a good place to start:

This sounds almost like a power supply setup for an ultrasoninc tool of some kind. I have had a fair amount of experience with the Branson line of ultrasonic welders.

Your risk factors at those frequencies are no different then what you need to worry about for a standard AC source.

Obviously... keep the wiring in good condition and keep the conductors that feed the loads clear of any grounded materials.

Thanks for the replies. Indeed I am having problems finding a relevant standard, there seems to be quite a gap in the research on DC/low frequency AC hazards and high frequency (RF) hazards, leaving, as someone noticed, the ultrasonic frequencies relatively poorly understood. The standards appear to reflect this gap, or at least don't treat these moderate frequencies separately.
There seems to be a "general" opinion that at higher frequencies, the shock hazards are lower, but the burn hazard increases. Fortunately in my case, any shock is likely to be constrained to a small area of contact between conductors, as the voltage is floating. What I can surmise from a large number of bits and pieces of info, is that the initial shock at this voltage would certainly provide a noticeable shock even on dry skin, with little muscular effect, but an increasing surface "burn" effect as the conducting skin resistance rapidly lowers.
I am certainly not planning to do any "live" experiments. :) (unless there are any volunteers...)
We will certainly adhere to the standard best practices for design and assembly of any industrial electrical equipment, and in this case likely over-design, but would be nice to understand the risks as they exist, say, relative to 60Hz.

Are you looking for a standard to use during your design and construction process? If so, I can point you in that direction.

your reply to BRich was a bit harsh. As you have only made 4 posts and you are new to this forum. You have not experienced the amount of people who post questions in the attempt to get other people to do their homework for them. You could have said in your Op, tried google, found nothing... but you didn't. and my guess is that you were pointed at doing your own work first

Of course there are the plain dumb people that no amount of help will EVERY sort out their problem or question.

Sarcastic remarks are not welcome here, and will quickly get you a reputation for being such and no cooperation from the forum.

Be nice is the word
