PWM Motor Speed Controller 4.5V‑35V DC Speeds Regulator Control LED Dimmer with Knob 0‑5A

Feature: 1. BASIC SPCIFICATIONS: The working wide voltage of the motor speed controller is DC4.5V‑35V, and the output power is 90W. 2. FORWARD AND REVERSE: The motor can be forward and reverse. When the operating direction does not match the expectation, you can adjust the line sequence to change the direction. 3. POTENTIOMETER KNOB: Adjust the potentiometer knob to change the duty cycle of the governor output, and the motor speed will also change. 4. APPLICATION: This is a motor speed regulator that can be used for speed regulation of DC motors, fans, etc. 5. HIGH EFFICIENCY: This is a mini DC motor speed controller with high efficiency and easy to use. Specification: Item Type: PWM Motor Speed Controller Working Voltage: DC4.5V-35V Output Current: 0-5A Output Power: 90W (Large) Quiescent Current: 7uA (Standby State) PWM Duty Cycle: 1%-100% PWM Frequency: 20khz Size: Approx. 30mm Length x 26mm Width (Without Handle) x 14mm Height / 1.18in Length x 1.02in Width x 0.55in Height Package List: 1 x DC Motor Speed Regulator 1 x Knob Caps 2 x Washer Note: 1. The input of the DC motor speed controller is DC and cannot be directly connected to AC (For example: 220V AC on the front page), otherwise will burn! 2. The positive and negative terminals of the DC power supply are not reversed, otherwise the governor may be damaged. 3. The motor can be positive or negative. When the operating direction does not match the expectation, the line sequence can be adjusted to change the direction. 4. Adjust the potentiometer knob to change the duty cycle of the governor output, and the motor speed changes.
