PWM (PWM) - a device that is necessary for a hydrogen generator HHO, to ensure the optimum performance and stability of its work.

PWM (PWM) manufactured by STAFOR keeps stable and constant current (regardless to the temperature or the concentration of KOH electrolyte), and shows the work mode of system on LED indicator (optimal/unoptimal).

Built-in electronic relay and adjustable automatic switch ON/OFF function.

STAFOR HHO PWM can be proud with features such as:

  1. Guaranteed optimum performance of your HHO generator or H2
  2. Automatic constant current (A) holding
  3. The indicator of the electrolyte concentration (KOH)
  4. Built-in LED ammeter
  5. NO MECHANICAL RELAY, PWM automatically switches ON/OFF
  6. Adjustable automatic switch ON/OFF function for each car individually
  7. Indication of a broken wiring connection
  8. Indication of minimal water level on PWM, without any additional sensors or floaters
  9. Automatic protection of HHO generator at low water level
  10. Built-in electronnic relay, can be used as additional PWM ON/OFF source

One of the basic and most important components of a good HHO system - it's PWM (Pulse Width Modulator). It is a small electronic device that connects in the HHO control circuit and manages the electric pulses that goes to HHO system, regulating HHO generator work current, for optimal HHO gas production.

The device (PWM) monitors current, prevents HHO system from overheating and allows your generator to produce more HHO gas. The device uses a heatsink and fan for additional cooling.

Pulse width modulation is a method of transmitting information on a series of electrical pulses. We recommend use of PWM to control HHO generator as it is energy delivery (to HHO generator) device via a pulse sequence and frequency change.

PWM (PWM) allows you to control work current of HHO generator in very simple way. Regulated, during intallation, work mode (current, A) of HHO generator will be automatical and stable thanks to PWM, the temperature of the generator will be low and lifetime of entire HHO system will be extended, in same time increasing its efficiency.

We recommend installing a PWM for all HHO generators.

What are the main benefits?

Efficiency. HHO generator will work more efficiently while consuming significantly less power (current, A)
Amperage control. Control of current in the HHO generator will keep the optimal it`s operation mode and will extend the life of the generator.

Technical characteristics
