Has anyone got or can anyone design a circuit for me.
It is to get 220vdc 5ma from a 9volt battery.
It is so I can build my own proving unit for my Electrical Inspection and Testing Kit.
It is basically to prove my tester is working after proving Electrical supply has been disconnected..
I am new here and I hope this request is in the right place..
