I bought one of these 24v DC motor controllers:
My question here is: it takes 12-24v DC in and with just a variac and bridge rectifier, it works. But would it work better with a regulated supply? I'm guessing not because of its own big cap and PWM output. But what do I know. If regulated would be better, in what way?
I don't want to just add caps because it will have very intermittent duty and the fully-charged cap voltage would be way over the controller's rated 24v.
Thanks, Bob
