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

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 MOS tube 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. Control power is optimal at 300W for 12V, 400W for 24V, 450W for 48V, and 500W for 60V. The PWM frequency is set at 12KHZ with an adjustable duty cycle range of about 1% to 100%.Colour:As ShownMaterial:MetalPackage Contents:1 set * DC Motor Speed ControllerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
