Good product
Of course, this is a used product, but it arrived quickly. I put a new battery in it and programmed the code. It works and works well.

HV power supply
1 of 1 found this helpful Surprising easy to use. The output looks like a pulsating
DC. Excellent for experiments with HV, such as Crookes Tubes,
or simple particle accelerators. I got an excellent response from
the seller. I received the HV supply in just a few days.
