Maximize Your HHO System’s Efficiency with Our HHO PWM Controller 150A Constant Current, Smart Monitoring & LCD Options

Looking to boost the performance and reliability of your HHO hydrogen system, galvanic anodizer, or decarbonizer setup? Our HHO PWM Controller 150A is engineered for powerful, safe, and automated operation—making it the ideal upgrade for any high-performance electrolysis system.

Intelligent Current Control for Stable Output

Designed with advanced digital regulation, the HHO PWM Controller 150A automatically adjusts the pulse width to maintain a true constant current—even in dense electrolyte environments. It supports systems drawing up to 150A peak, with stable 100A continuous current, preventing thermal runaway and extending the life of your components.

Compatible with both 12V and 24V systems, the PWM controller uses four oversized 120A MOSFETs and features ultra-efficient power handling with minimal heat buildup.

LED Feedback for Instant System Insight

Stay informed with a smart LED status system:

• Solid ON: Normal operation
• Slow blink: Low water level – refill needed
• Fast blink: Low HHO output or system error

The system also supports automatic water level sensing. When connected to a water level switch, the PWM will only activate if water is present. If not, the display shows “LOV” (Low Volume), keeping your system protected at all times.

Upgrade to the LCD Display Version for Full Control

With the LCD display version, you can monitor and configure your HHO system directly from your dashboard. Ideal for automotive installations, this version gives you real-time insights and deep parameter control.

LCD Menu Settings Include:

• Output cell current
• ON/OFF voltage thresholds
• Water level sensor toggle
• MAP correction ON/OFF
• MAP current multiplier
• Voltage sensing input toggle

Install once, configure once—and enjoy continuous, hands-free operation!

Key Technical  of the HHO PWM Controller 150A

• Constant current regulation across all temperature levels
