WA6-30N High Voltage Enable
Posted: Thu Jul 05, 2018 9:11 am
Have been working on getting my 30kv/20ma power supply working. It's a Matsusada unit, all controlled via a fairly simple I/O. Datasheet is attached.
My first step has been trying to get the HV status pin to LO, which means HV ON. As far as I can tell from the datasheet, this only requires shorting the interlock (pin 7) and remote switch (pin 21) to their common pin 17. To check this I have circuits as shown in one of the attached images. They don't seem to be working though. The LED connected to the HV Status is lit up and does not turn off when the interlock and switch are shorted. Can anybody see if I'm missing something? I've also attached pics of the Dsub connector, to which I've soldered my connections.
Thanks.
