A Simple Time Delay Circuit

I finally decided to add another line to my charge controller and I wanted a steady power output instead the PWM that comes off of the dump controller so I made this handy little circuit to take a PWM signal and change it to a constant DC signal. Gather the Materials To build the basic(…)
