I bought one of these and I not sure of how well it works. It worked, yes, but I find its output suspect.
It is the first that I've bought, so I don't really have anything to compare it to. I'd be interested in what feedback you get on this.
Found this site with the same unit as a DC motor control. I don't think that unit is really designed with hho optimization in mind...?

2008 Nissan Frontier 4X4 Nismo. 12 MPG baseline with my normal commute and heavy stop and go daily driving. Generator installed and working on 3/29/2009
Up to 14.5 MPG with no enhancers. Still testing the effects of lots of HHO and no electronic enhancers.
Many so called sellers on eBay and elsewhere who sell PWMs do not have even a little idea on what they sell and how the PWM modules do work. What they do is simply resell somebody's product.
For example http://www.canakit.com/ has their own 50A PWM that is very affordable in price and well designed. I bought one and tried it. BWT, other guys sell it as their own product on eBay!
Keep in mind that most stock PWM units are Motor Control devices (http://www.canakit.com/electronic-ki...or-controllers) and the mosfets work OK in any duty cycle driving motors, but not close to 0 Ohms HHO Cells that put huge load on the power rail...

Thanks for the link. That looks like it would not be too tough of a kit to tackle. And the board layout would make for easy component replacement. Although I would not use spade connectors for hook up.

Hi Guyz
I have a 30amp PWM with Ajustable Frequency Control that I have not yet attatched to my Cell. Will the feature on this PWM help more in controling Voltage, Amperage Ect Ect Ect & help in fine Tuning my Cell's output?
Hope to hear from sombody soon as I want to hook the divice up to my Cell soon. Many Thnx. E"!"
Erik,
The PWM will allow you to dial in the amount of amps your cell is pulling. It works by rapidly switching the ground of the cell off and on. One benefit is that you can put maximum strength electrolyte in your cell and just dial in how many amps you want. KOH at 28% by weight will give excellent freeze protection as well as make your device more efficient by reduced resistance.
