Pulse Width Modulators or PWM can limit the amount of current that an HHO generator draws and keep it from going beyond a set amount. It controls the amount of amperage your hydrogen generator uses. The higher the frequency generally the more efficient you HHO generator will be with less current while controlling temperatures.
You may have asked yourself what is the purpose of using a 30 amp pulse width modulator with a HHO generator? PWM controllers help to maximize HHO gas production with available current. You can also use 60 and 80 amp pulse width modulators for larger projects.
A PWM pulses the plates of your HHO generator several hundred or thousand times per second. By doing this you can use lower voltage and less current and the electrolyte operates at a lower temperature.
