My new 144MHz amplifier needs a power supply. I came accros this nice power supply, it was used in Plisch TV transmitters and designed to last for ever in a 24/7 environment.
It's a 3 Phase power supply with an output of 4.3KV and arround 1Ampere. There are several protections and other circuits but I don't know yet how all needs to be hooked up. I have a bad copy of the diagram and that's all. I allready found out how 400V needs to be connected and with latest rise in mains I allready connected the transformer to the next higer tap of the transformer 405V instead of 380V tap, to be sure output voltage is not way to high..
There are 2 30pin DIN connectors at the rear X1 is for mains connection and X2 for control voltages and meter connection. Have to figure out how to connect this connector.
a little progress, Found out some things about the connectors on the rear :
The inside is very solid build as you can see..
