I'm currently building a DIY variable voltage / current power supply. Using a cc / cv buck converter and a LED volt / amp meter...
I would like to have meter to show the amp value before I power the load... So instead of it showing the Value only while the load is being powered...
I am assuming the only viable way of doing so is to hook up a momentary switch that is wired to a power resistor so I can hold the switch and adjust the amp output of the buck regulator so it'll read out on the meter. Correct?
If anyone has any ideas on how I could do this so it always shows the selected amps without constantly powering a power resistor...
And I plan on removing the potentiometers on the buck regulator and installing two bigger ones I'm the outside and the power supply so I can easily adjust them.
Thanks
