# What is the most economical way to have a power supply providing voltage up to 3kV and current up to 1-2 mA?

I need to perform some physics experiments and need a regulated DC power supply which can produce voltage in the range of 200V-3kV and current up to 1-2 mA.

What is the most economical way to have such power supply? I couldn't find anything like this on EBay/Amazon, but I can easily solder things myself if needed.

This is not exactly a low budget weekend hobby project. The components are going to be expensive, especially when purchased in low volumes. I question your choices of Ebay and Amazon as primary sources for a specialty product like this.

Let us set aside economics for the moment.

One usually begins with the standard laboratory benchtop HV supply.

One can purchase similar supplies in a modular format.

As @MrChips has so adequately demonstrated you don't go to bargain retailers for specialty products. There are many more out there; you just have to expend a modicum of effort to find them.

I got all my HV supplies used. One is a "Hi Pot Tester".

I thought I'd filtered out the "for parts" items, thanks for catching that.

As far as the price, though, affordable is relative and for what it is, that's very affordable (which is explained by the condition!).
