30 amp PWM


30 Amp PWM


This is our new 30 amp Max PWM with a fan
for boosters that draw less than 25 amps.


Over 300 Sold

By using a PWM (Pulse Width Modulator), your hydrogen booster will run cooler and make more monoatomic hydrogen than with just using direct current alone.

Monoatomic hydrogen has greater ability to increase fuel mileage than regular hydrogen (diatomic).


This little PWM will reduce the current draw of most boosters and also help your booster to run cooler and make more monoatomic hydrogen than using 12 VDC alone.

Recomended for cells that use less than 25 amps
(9-12 plate dry cell)

If your cell uses 30 amps please buy the 35 HD PWM


* Rated for 40+ amps peak 20-25 amps RMS.

* Fully adjustable pulse width from 0 - 100%.

* Two 80 amp (peak) mosfets and two heat sinks.

* Voltage 12/24 VDC. (fan is rated for 12-18 VDC)

* Output frequency is preset at approximately 100 HZ.

* Circuit board size = 3.85" x 1.59"

* Circuit board has extra thick traces to improve current flow.

You will need to connect the wires yourself. To do this,
unmount the board by removing the two screws and the pot retaining nut to make the connections to the PWM.

To connect the PWM, just feed the wires through the large holes in the back of the box. Connect the two power wires to the outside spade connectors making sure the + wire goes to the + spade on the PWM and connect the HHO generator to the inside two spade connectors.

Chrome fan grill is included.
Wire and relay not included.

This unit is fully tested and ready to be installed.

Guaranteed No DOA
