FYI, you can buy `power supplies' for use in Hi-Potters, 120 Volts ac in
10/20/30 kV out
all sealed in a can. Check Allied, Newark and etc., at one time one or both
sold them.
> I want to order 10 HV transformers for my portable hi-pot tester(the
> manufacturer's minimum order is 10 pcs).
> Anyone would like to share these with me?
> Specs:input(220/110V 50Hz, 65/130mA),output:7000V .
> weght:850g,Core:Hypersil;WxHxD=95mmx70mmx55mm.
> Type: leak magnetic transformet(that means you need not put a bulb to limit
> the short circuit current),core:
> Hy-persil. Price:$32/ea.Shippingcost:about $10-30 depend on the
> way(surface,sal and
> air mail).
> And I just got some thins for this: HV diodes :16KV/5mA $85C/ea, HV

> (made by Matsushita,this capacitor was used as plate block capacitor in my

> $1/ea. And I can supply HV resistor 51M/6W(can hold 18KV),$2/ea.
