30A PWM DC Motor Speed Controller, 7-70V Adjustable Variable Switch

Versatile Voltage & High Current: This PWM motor speed controller operates efficiently across a voltage range of 7V to 70V and supports currents up to 30A. It includes an integrated switch with run, stop, and brake functions, and a detachable 15 cm potentiometer adjustment wire for precise control. Optimized for Continuous Operation: Designed for stability and noise-free performance, this controller features a broad duty cycle adjustment range, ensuring smooth motor operation. It's equipped with a power indicator and is ideal for applications requiring long-term continuous use. Durable & Reliable Construction: Built with a high-voltage MOSFET and three 100V high-frequency low-resistance capacitors, this unit includes automotive fuses for easy replacement and a robust aluminum shell to protect internal components, ensuring longevity and reliability. Installation Guidance: Ensure correct setup by following the detailed wiring labels before power connection. The controller requires DC input with correct polarity, and motor connection is polarity-free. If motor direction is incorrect, simply swap the two motor wires. Technical Specifications: Applicable for DC 7–70V, with a maximum drive current of 30A. The PWM frequency is 12 kHz with an adjustable duty cycle range of approximately 1% to 100%.
