<div class="a11y-text-width js-read-more js-product-description Product__Description-text text-break" data-lines-to-clamp="4" data-device="mobile">[Wide Voltage]: Input range of 7-70V, maximum output current of 30A. Recommended power: 12V up to 250W, 24V up to 350W, 48V up to 450W, and 60V up to 500W. <br>[Speed Control Knob]: Features a switch for motor speed adjustment from 0% to 100%. The adjustable potentiometer has a detachable 15CM cable. <br>[30A Fuse]: Includes a 30A fuse for motor interface protection, ensuring double safety for both the Motor and Speed Controller. <br>[Note 1]: Input supply power must exceed 1.5 times the motor's rated power for operation (ensure input and motor voltage match). <br>[Note 2]: For children's cars with forward-reverse regulators, connect the speed controller between the power supply and the regulator to avoid damage. <br><br>Precautions:<br>This module is for DC motors only; do not connect to AC power. Ensure input supply is 1.5 times the motor��s rated power and voltage match.<br>Modification for Children's Car: To enable forward and reverse control, the speed controller can connect to a Forward and Reverse Switch. Always place it before the forward-reverse regulator in children's cars to prevent damage. <br>Specification:<br>DC Motor Speed Controller<br>Voltage range: DC 7-70V<br>Maximum drive current: 30A<br>Recommended control power:<br>12V: 250W max<br>24V: 350W max<br>48V: 450W max<br>60V: 500W max<br>Adjustable duty cycle: 1%-100%<br>PWM frequency: 12KHz<br>Fuse: 30A max<br>Wire details: 2.5mm2 / 0.4cm diameter / 12AWG<br>Wire length: 26cm (total length including 30cm)<br>Material: ABS<br>Color: As shown<br><br>Package Includes:<br>1 x DC Motor Speed Controller<br><br>Only the contents listed above are included.
