PWM DC Motor Speed Controller with Digital Display, 30A Adjustable Stepless Regulator 1. This motor PWM speed controller features screw terminals for easy installation. 2. Input voltage range: DC 6V–60V (compatible with 12V, 24V, 36V, and 48V power supplies). Output current: 0–30A. Not compatible with AC 110V or 220V mains electricity. 3. LED digital display shows the output speed as a percentage of maximum speed (0–100%). For accurate operation, input voltage must match the rated voltage of the connected DC motor (within 6–60V). 4. Dimensions: 13 x 6 x 3.2 cm (5.1 x 2.4 x 1.2 in) — controller; 4 x 1.8 cm (1.5 x 0.69 in) — button switch; 23 x 20 mm (0.9 x 0.77 in) — potentiometer; 15.5 x 23.5 mm (0.6 x 1.0 in) — knob; inner knob hole diameter: 6 mm. 5. Includes a momentary start/stop switch, speed control potentiometer, and knob for smooth, stepless speed adjustment.
