Our 120 amp PWM
Can Power Multiple Cells Up To 10 LPM!


Hydrogen Boost Now is pleased to offer our new heavy duty 120 Amp PWM. This PWM has the ability to adjust output frequency independently of the duty ratio. The unique 'Remote Power On' feature allows you to turn the PWM on and off with the ignition by running a small wire to the ignition switch. The remote wire will draw less than 1 amp, which eliminates the need for a large relay. This PWM can run multiple cells to maximize your HHO production.


The PWM circuit controls the duty ratio from 0% to 100%. The max output current is rated at 240+ amps peak or 120 amps continuous!


Remember, when a booster draws 60 amps of current using a PWM set at 50%, that is the RMS value not the peak value. The peak value is about 120 amps.


* Remote power on:10-18 VDC
* Output Voltage: 8- 30 VDC output
* Output Current: 0 - 120 amperes continuous, 240 amps peak!
* PWM switching frequency: 300 Hz - 15,000 Hz (adjustable)
* Duty ratio 0% to 100% (for adjusting max output)
* Power switch with red LED
* Mounting tabs
* Input power for remote power on 1.25 amps peak at 12 VDC
* Physical dimensions approximately 10" x 7" x 3" all heat sink
* Weight Approximately 5 lbs
* Made in the USA By Hydrogen Boost Now.
