Advanced PWM Technology: Achieve precise control over the speed of your DC brushed motors using cutting-edge PWM pulse width technology. This controller allows for a 0-100% duty cycle adjustment, enabling stepless speed regulation across applications including industrial, DIY projects, and experimental setups. Broad Voltage and Power Range:Compatible with a wide voltage input from 7V to 70V,this controller supports multiple DC configurations (12V, 24V,48V, 60V). It handles up to 30A of drive current with dual 30A fuses for enhanced safety.Power ratings are optimized for different voltages:12V up to 300W,24V up to 400W, 48V up to 450W, and 60V up to 500W. Enhanced Circuit Design for Durability: The controller features a robust circuit with high-voltage MOSFETs and three 100V HF low- capacitors. Encased in an aluminum housing with a waterproof fuse box and replaceable fuses, it ensures reliable, long-term performance even in challenging environments. Triple-Safety Mechanism: This device is designed with a focus on safety, featuring overcurrent and short-circuit protection that automatically cuts off in case of faults. The aluminum housing is designed to withstand impacts and , operating effectively within a temperature range of -20°C to 60°C. User-Friendly Interface: Equipped with a 3-position switch (RUN/STOP/BRAKE), this speed controller allows for quick and easy mode transitions. The removable cover and flexible potentiometer wiring are designed to accommodate complex installations, simplifying setup and adjustments.
