that’s a cool find for stepping down the power. Is it a constant DC output, if the input AC varies? I power my track with a z4000. Somewhere between 18 and 22 Vac. I’m definitely not consistent.
thanksMarty
@Marty R I can answer that, The voltage you chose with the little screw potentiometer is fixed to within a few thousandths of a volt. I just tested an almost identical buck converter board on my Z1000 transformer and as long as the transformer was putting out more than 6 volts I was getting an almost perfect constant 5 volts output. That regulator can handle more than these transformers put out. Just test with a meter to make sure you have the output dialed in correctly first since these are adjustable regulators.
