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 for clear, precise reading. Input voltage must match the rated voltage of the connected DC motor (6–60V). Dimensions: - Speed controller: 13 x 6 x 3.2 cm (5.1 x 2.4 x 1.2 in) - Momentary switch: 4 x 1.8 cm (1.5 x 0.69 in) - Potentiometer: 23 x 20 mm (0.9 x 0.77 in) - Knob: 15.5 x 23.5 mm (0.6 x 1.0 in), inner hole diameter: 6 mm - Panel cutout: 92 x 56 mm - Overall unit size: 95 x 60 x 33.8 mm - Cable length: 18 cm - Net weight: 120 g - Housing material: ABS - Color: As shown Speed Control Specifications: - Control method: Potentiometer - Speed range: 0–100% - PWM frequency: 15 kHz - Wiring type: Screw terminal - Digital display: 0–100% speed percentage Package Includes: - 1 x Speed controller - 1 x Momentary start/stop switch - 1 x Potentiometer - 1 x Knob Notes: - The digital display shows speed as a percentage, not absolute motor RPM. - Ensure correct polarity (positive/negative) when connecting input power. - This device is for DC use only — do not connect to AC mains (e.g., 110V or 220V household electricity). - Input voltage must match the motor’s rated voltage (within 6–60V DC). - Actual product color may vary slightly due to lighting and screen settings. - Dimensions are subject to a tolerance of ±.
