40A DC Motor Speed Controller PWM

The 40A DC Motor Speed Controller PWM is a compact, efficient controller that gives you smooth, reliable speed and direction control for DC motors ideal for robotics, conveyors and custom DIY power projects (SKU MOD-176).

• Key benefits: Efficient PWM switching reduces heat and improves battery life while delivering consistent torque across the speed range.
• Easy control: Intuitive potentiometer speed adjustment with a forwardbrakereverse switch for instant directional control.
• Robust performance: Designed for continuous 40A operation with shortterm higher surge capability so motors run cooler under load.

Use the MOD-176 to upgrade go-karts, electric scooters, conveyor belts, workshop tools, DC pumps or hobby robotics where responsive speed modulation and reversible motion are required. Its compact footprint and screwterminal wiring make installation straightforward in enclosures or control panels.

Technical highlights include a wide DC input range (typical 1055V), PWM frequency around 15kHz for low audible noise, digital percentage display for dutycycle feedback, and solid MOSFET switching with heatsinking for sustained 40A continuous current and higher shortterm peaks (60A max rating on similar modules). The unit measures roughly 100128mm by 7698mm and connects via labelled power and motor terminals for safe, simple wiring see SKU MOD-176 for specs and compatibility before installation.
