New Power Supply

Post by Cameron Palte »

Hello everyone,

Would $2500 be a high enough budget to purchase a new power supply for achieving fusion from Spellman or Glassman or a company like that?

Probably, but if you spend some time searching you could find a used supply for a lot less. Or you can do what a lot of people on here do and build one.

If you must spend big bucks just make sure you over-buy. Go for a minimum of 40kv at 15ma or more. Do not buy a 30kv, 10ma supply, you will regret it. This assumes you are serious about doing real fusion and sticking with it for a while.

Hello,

I got a quote on a Spellman SLM 40 kV 30ma 1200w power supply (negative or positive polarity you specify at time of order). http://www.spellmanhv.com/en/Products/M ... W/SLM.aspx

Is this supply is suitable for real fusion? Because I read that you said you should get more than the minimum ma because of current limiting many large manufacturers do.


Thanks,
Cameron

The supply should be quite sufficient.

It depends on how the current limit works. If it shuts down the supply when the limit is exceeded, it will be very annoying. If it just limits the current to the specified value, that's fine.
The more reactive the materials, the more spectacular the failures.
The testing isn't over until the prototype is destroyed.

Just set your current limit for max and you will be OK provided you don't have any electron emissive runaways or pulsing.

Most problems occur when folks order a 10ma unit or even a 20 ma unit. At 30ma, if you are a good driver/operator of your fusor, you should have little to fear with the annoying trip out overcurrent protection.
