This Motor PWM Speed Controller features screw terminals for easy installation. Input Voltage Range: DC 6V–DC 60V (compatible with 12V, 24V, 36V, and 48V power supplies). Output Current: 0–30A. LED Display shows the percentage of actual speed relative to maximum speed. Input voltage must match the rated voltage of the connected DC motor (6–60V). Dimensions: 13 x 6 x 3.2 cm (5.1 x 2.4 x 1.2 inches). Momentary start/stop switch, speed control potentiometer, and knob included. Enables smooth, stepless speed adjustment. Speed Control Type: Potentiometer-based Speed Range: 0–100% Control Frequency: 15 kHz Terminal Type: Screw terminal Cable Length: 18 cm Net Weight: 120 g Panel Cutout Dimensions: 92 mm x 56 mm Digital Display: 0–100% speed percentage Color: As shown Material: ABS Product Dimensions: 95 x 60 x 33.8 mm Package Includes: 1 x Speed Controller 1 x Momentary Start/Stop Switch 1 x Potentiometer 1 x Knob Note: - The digital display indicates speed as a percentage, not absolute motor RPM. - Input polarity must be observed (positive and negative connections correct). - Not compatible with AC mains voltage (e.g., 110V or 220V). - Input voltage must match the motor’s rated voltage (e.g., 12V motor requires 12V input; 36V motor requires 36V input). - Color may vary slightly due to lighting and screen settings. - Measurement tolerance: ±1 mm.
