HHO PWM 55A LCD

Optimize Your HHO System with Our HHO PWM 55A LCD – Constant Current, Intelligent Regulation, LCD Display Option

Looking to enhance the performance, safety, and reliability of your HHO hydrogen, galvanic anodizer, or engine decarbonizer system? Our Digital HHO PWM Controller is engineered for maximum stability and consistent output, even under demanding operating conditions.

Constant Current Control for Superior Stability

Equipped with a high-speed 32-bit Cortex processor, this intelligent controller automatically regulates the pulse width to maintain a constant current, effectively preventing thermal runaway in any HHO cell or anodizer drawing up to 55A peak / 40A average. Whether you’re running dense electrolyte solutions or lightweight setups, this controller guarantees optimal efficiency and long-term reliability.

Compatible with 12V and 24V systems, and designed to handle serious loads with oversized 60A MOSFETs, this unit runs cool—with a temperature rise of just +15°C at 20A—thanks to its ultra-efficient design.

Water Level Safety & Smart Start Logic

Stay safe and in control:

• Connect a water level switch to prevent the system from running dry. The PWM only activates when the level is sufficient.
• The controller also features key switch activation – it powers up only when voltage is supplied to the designated terminal.

LCD Display Version for Full Dashboard Monitoring

Upgrade to the LCD display version and take full control from your car’s dashboard. Easily monitor your HHO system in real-time and fine-tune key settings via an intuitive menu interface.

Adjustable Parameters via LCD Menu:

• Output cell current
• Turn ON voltage
• Turn OFF voltage
• Enable/disable MAP-based correction
• MAP gain multiplier
• Enable/disable water level sensing
• Enable/disable voltage sensing input
