PWM (Pulse Width Modulators) For HHO Generators

Why Use PWM's for HHO Kits?

The PWM has become the new standard for current control for advanced HHO Kit enthusiasts. Rather than just straight current flowing into your generator, these PWM boards control current and the resulting heat that can sometimes be a problem, by pulsing off and on rapidly. Some pulse at a fixed frequency, with current adjustable. Others allow both current and frequency to be controlled like our Heavy Duty 30 amp and the monster 50 amp below.

Our new Hybrid Cell HHO Generators do NOT need a PWM because they are so efficient they don't overheat (which is the reason many designs need to use them). However we still have a lot of people who like the extra control gained by using one.

If you have your own HHO Generator or bought an HHO Kit from someone else, that's OK - we forgive you. You can still buy a PWM from us.

30 AMP PWM (Pulse Width Modulator) For HHO Kits

Retail: $69.95  SALE: $49.95

This 30 AMP PWM works great for Electronic Control of your HHO Generator. Works with either 12 or 24 volt systems. Adjust your current from 0-30 amps for ultimate control of the hho gas production in your hydrogen generator. Operates at 100 HZ. We recommend a small computer chip fan on the heatsinks to draw away the heat for longer lasting board. Great entry level board for your hho kit.

Fully assembled and tested - NOT a kit! Ready to put into a hobby box or container. Comes with instructions how to hook up to your HHO Kit or HHO Generator installation.

Heavy Duty PWM 30 AMP(Pulse Width Modulator) For HHO Kits

Retail: $89.95  SALE: $69.95

This is the Heaviest Duty 30 Amp PWM we could find. It uses 2 terminals per output to double size of wire going to your hydrogen generator. Massive heat sinks draw heat away. Dual Control gives you more experimenting quality - one for current draw (up to 30 amps) and one to adjust frequency from 400 HZ to over 1000 HZ for experimental tuning to tweak production of HHO gas. Great Mid-Level board for experimenters and installers.

Fully assembled and tested - NOT a kit! Ready to put into a hobby box or container. Comes with instructions how to hook up to your HHO Kit or HHO Generator installation. If you want one pre-assembled in a box with fan, see below.

50 AMP Ultra Duty PWM (Pulse Width Modulator) For HHO Kits

Retail: $189.95  SALE: $149.95

The Mother of All PWM's! This monster puts out 50 Amps of Pulsed Current with 6 mosfets and a gigantic heat sink to pour as much power as you need into your hho kit.
Dual Control gives a wide range of experimentation by combining current control with frequency adjustments. This one goes from fixed 100 HZ to 4000 HZ! The manufacturer makes this one with 3 spade fittings per output/input so you have fully 12 connections which keeps heat down. You can split the wires going and out, or run 2 HHO generators. For Serious Hydrogen Experimenters! This is a good one to use for a dual HHO generator set up

Fully assembled and tested - NOT a kit! Ready to put into a hobby box or container. Comes with instructions how to hook up to your HHO Kit or HHO Generator installation.

PWM Assembled in a Project Box!

Retail: $109.95  SALE: $97.00

We've had some recent requests to offer completely assembled PWM units so we found a supplier to build these nice units. They are built using the Heavy Duty 30 AMP PWM like pictured above and come with a fan, switch, and dial controls for adjusting the current AND frequency (Actual product may vary from picture).

These are nice units and come with ventilation slots cut into the sides to allow air to be drawn up and over the cooling heat sinks. Holes are pre-drilled in the back for the wires and connectors to attach to the board inside.
