PWM70 can handle up to 70 amp continuously. It will run two cells or just one. It can handle 100 volt spikes. This new version made at Hydrogen Garage has two mosfets and drivers that keeps it cooler and a sharper square wave. It has "current limiting" capabilities. It has freq. adjustment (100hz. to 500hz) and duty cycle adjustment. Excellent choice for a diesel trucker application. Internal fan keeps it running cool. Now features two outputs. 2 power mosfets, large 12K capacitor, extruded aluminum 1/16" thick walled box. Heatsink, fan, a hardy PWM that will not burn up. Can handle the 24/7 trucker ride, if mounted in a box or compartment. Works good with our 80 amp relay, or 200 amp relay. Designed by Pete Hemmi. We call the PeteWM current limit controller.
Add a set of RF Chokes and get a taller voltage spike that creates 10% to 15% more gas output! and a higher quality gas to boot! Does NOT draw any more amps, or volts, just makes more GAS!! Install between your PWM and your cell.
Also available with a digital ammeter.

and guaranteed to keep on working, if hooked up correctly.
We can guarantee you a good % of "Ortho" hydrogen from our a Bob Boyce® 7 plate, low voltage cell designs. The main purpose of the PWM in electrolysis is too make this magnetic spin state of hydrogen & oxygen, that clings to nitrogen, oxygen and bonds to carbon like glue. 100% ortho hydrogen is 4x's+ more powerful than 100% para (tank) hydrogen!! Also with this PWM, you can set the amp draw and it will stay close to what you set it, no matter the electrolyte concentration
With the "current limited" PWM70 and PWM30 your cell will always be at the same amperage, that you set. It will stay close to the amp you set it. As your cell heats up and more amps shuld be draw, the PWM automatically adjusts the "duty cycle" down. Your cell stays at a constant set current, no matter cold and hot.
