Cheap pump regulators

[nicmac888]

Hello!
So I have two pumps like this one that came with two AC adapters (13.5V - 1.5A)
The same company sells speed regulators for like 30 bucks each, but I was wondering if one of those 7$ regulators would do the trick.
Any other ideas?
Thanks

Yes, that would work. A DC motor's speed can be controlled by varying the voltage applied to it. These "regulators" are simply solid state relays that duty cycle (pulse width modulation) the amount of voltage applied to the motor. 60 watts at 12 volts means that it can handle 5 amps, which should handle that pump just fine.

I use these...they are half the price of what you linked

Been using three of them for my 12v and now 24v pumps for a year now. They work great.
Also use two similar ones for my stir bar and stirring rod builds.
The frequency of the pwm does matter... the smaller led dimmers won't work well

Thanks guys!

I will be getting a 2 or 3 of the ones you linked to augiedoggy. They also seem to be easier to mount on a future panel!
