new gimmick I thought ide share. I had an old speed controller laying around and nothing to play with in the shed, thought ide wire it up to my 12v system. Had a play with it works great, please keep the ridiculing to a minimum it’s just a bit of curious fun
That’s actually really neat, can those pumps operate ok at reduced voltage?
Yes, but to a point I believe. The speed of the motor controls the liquid output. I could see it being handy when having to pre or post treat smaller areas to control run off, heck even roofs. I’m not sure I’ll be putting much effort into it, I hate electronics on my rigs.
That is a thing over here already, I believe it’s called a control wizard, and others have rigged up a speed controller for there WFP 12 volt systems, actually quit common
I believe @Infinity made his own
I’ll have to dig it up, sounds like a good read.
Yeah. PWM motor controller. On amazon for $15-20. Check your amp ratings to make sure it will support your pump
My vendor told me I had to make sure to run the pump on a good strong battery as if it was operated with less voltage it could be detrimental to the pump. I hope he’s wrong and would love to have that flexibility. Can anyone confirm if what he told me is true?
I would probably be more worried about not flushing it after using it than what the vendor told you.
PWM stands for Pulse Width Modulation. You can do your own research on the way it works if you want, but basically, it doesn’t change the voltage at all. It breaks the current up into rapid pulses. PWM was designed specifically for devices that rely on a specific voltage to operate correctly, such as LED’s and 12v motors.
