30 Amp PWM


Now Frequency Adjustable


Heavy Duty 80 Amp
Pulse Width Modulator
With Frequency Adjustment


   This is our 80 amp heavy duty PWM..

A PWM (Pulse Width Modulator) is used to control the amount of HHO that our boosters produce and can make any booster produce 2-3 times more monotomic hydrogen than just using direct current. Also, most HHO cells will run cooler and draw less current with a PWM than just using direct current alone.

This PWM comes with very large mosfet transistors.

These Mosfets cost 10-20 times more than a cheap transistor but we wanted a part that would last for years and be easy to service for our customers.
Shipping weight of 1 Mosfet - 28 grams! Shipping weight of the mosfet used on the 30 amp PWM - 4 grams.

Our 80 amp heavy duty PWM will handle almost any HHO cell and is rated for over 900 watts this means you can make up to 7LPM of clean burning HHO with this pulse width modulator.

This 80 amp PWM also comes with a remote power on feature which eliminates the need to use a relay when connecting your cell. This makes for a nice clean installation.

The 80 amp PWM circuit controls the duty ratio from 0% to 100%. The output current is rated at 200 amps peak and 80 amps continuous current!

Note: When using a booster that draws 40 amps of current using a PWM set at 50% that is the RMS value, not the peak value.
The peak value is about 80 amps.
