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

Versatile Voltage & High Current: This PWM motor speed controller operates 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. Design Features: This controller features a duty cycle adjustment range for motor control. It is equipped with a power indicator. Construction Materials: Built with a high-voltage MOS tube and three 100V high-frequency low-resistance capacitors, this unit includes automotive fuses and an aluminum shell housing. Setup Instructions: Follow 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, swap the two motor wires. Technical Specifications: Compatible with DC 7-70V, with a maximum drive current of 30A. Power capacity is 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 approximately 1% to 100%.
