Power Supply

  1. Is it unreasonable to buy or build a power supply circuit that is rated at 500V and 4Amps?

    Thanks.

    I know 500V is possible, but not at that high an amperage.

    Anything in and around $5k would be fine.

  3. Yea, would be alot cheaper to build one.

    The problem would be finding a suitable step up 2000 W transformer to do the job.

    But there is a way to get around that,

    A simple step down transformer from 120 volts to 30 volts when connected in reverse will step up 120 V to 480 V. (turns ratio is 4)

    Assuming the insulation holds up, you might get up to 1 amp from one transformer.

    You would need four or more of these set ups in parallel to generate the required amperage at 500 V.

    After you rectified them, you a simple transistor regulator.
     
  4. I dont care about price, I just want it to work.
     
  5. yes, will a little tinkering and tweaking could be done well under $500 bucks.

    I dont want to tinker, or tweak. I just want something that works.

    If you know of any power supplies or circuits that would do what I want, please let me know.

    You are in an enviable position. Check out Lambda's high-power line; they have a 2.5kW supply that puts out 0-600VDC at up to 4 Amps, and others that will address your needs too.

  8. Yes, you are the man sir marcusl.

    This is EXACTLY the reply I was looking for, thank you!

    Have you tried Agilent? They make (or used to?) some big ones like what you want. Check their website or give them a call. And don't expect to drop anything short of $5K...unless you build it yourself.

    EDIT : Wrote this post when I hadn't yet seen marcusl's suggestion.
