What Is A HHO PWM?

PWM is a relatively recent technique, made practical by recent electronic power switches. Pulse Width Modulation is engaged in a wide variety of applications, ranging from measurement and communications to power control and conversion.

A pulse width modulator works by transmitting data on a series of pulses. The information being transmitted is encoded on the width of these pulses to control the amount of power being sent to a load.

They work by switching the voltage to the load with the appropriate duty cycle; the output will maintain a voltage at the desired level. A true PWM is just an electronic switch that turns on and off at an extremely quick rate of speed varying the percentage of time on vs. the time off.

To the load it appears smooth because it's so fast, just like our vision can barely detect the flicker of a fluorescent bulb even though it goes completely off and back on again 120 times a second. The duty cycle of a PWM is the percentage of on-time vs. off-time.

How HHO PWM Benefits Hydrogen Generator Systems

There is more than one benefit to your electrolyzer (or hydrogen generator) using a PWM. It doesn't matter how efficient your HHO generator is, they all warm up the longer they are run. If you were to run an engine for 8 hours straight, by the end of the eight hours, your generator will probably be as much as three times warmer than when you started.

Keeping your HHO system running cool is top priority. If you don't you will start to have an array problems.

The PWM will keep your current averaged out making your HHO system run cool and smooth.

You will also be able, with a quality PWM and electrolyzer, to achieve "Ortho" hydrogen gas. Ortho HHO gas is approximately 3 -4 times more combustible than para hydrogen. This is a much better quality of HHO gas as it provides improvement in combustion efficiency.

Where things start getting ugly is when booster quality is so poor that the energy required to produce the gas exceeds the amount of efficiency gained, and/or ortho hydrogen gas percentage suffers.

HHO PWM with LCD Display and Wiring Kit

$249.95
Constant Current PWM with LCD Controller
and Wiring

This PWM and LCD Controller serves multiple functions to accurately manage any hydrogen on demand system. Whether you are buying a system from our company, someone else, or building your own. Our HHO PWM and Controller Features:

• Capable of turning your HHO system off and on with a flip of a switch.
• You choose current or duty cycle
• A constant current pulse width modulator. Will not go over the maximum current the driver selects to run his HHO System on.
  When the current tries to go above the maximum current value, the duty cycle automatically reduces to maintain the current at its set maximum value. This puts a stop to current run away that has been a widespread problem with other HHO systems and PWMs
• In your cab LCD display controller that allows you a continuous read out of your hydrogen on demand systems Amps, Volts and Duty Cycle.
• A 40 Amp fuse to prevent an over current condition from damaging your equipment or wiring.
• This HHO PWM can control multiple cells (up to 50 amps). If running your PWM over 30 amps you will need to use a larger fuse than the one we include. 30 amps should be enough for passenger vehicles.
• The LCD Display Controller can control multiple PWMs. In this way you can run multiple cells or groups of cells at a higher total amperage.
• Safety Shut-Off - Two ways to detect when the engine is not running, and shut itself down, this is a critical safety feature.
