Review on Greartisan 6V-90V 15A PLC DC Motor Speed Controller PWM Variable Speed Regulator Governor Switch CCMHCN With Speed Control Knob by Larry Lackings

Edit - June 20, 2020 Product works as advertised. I apparently did not understand what I purchased and what it actually does vs what YouTube videos told me it should do.Does not function correctly. This unit only outputs the input voltage. The terminals register 0 voltage until the knob reaches the input voltage. Then nothing changes the further you turn it. Unfortunately, it took me a while to get the pieces for my power wheels battery conversion project together. I went to hook it up today only to find out that the return window closed yesterday. Frustrating!
