Feature:1. VOLTAGE AND CURRENT: Motor governor input voltage range from 10‑60V, output current range from 0‑20A, maximum power is 1200W2. MAIN APPLICATIONS: DC motor driver can be used for DC brushed motor, LED lights, DC brushed fan regulation3. ROTARY SPEED CONTROL: The motor control board can adjust the motor speed through the potentiometer; Adjustment range from 5%‑100 percent, potentiometer knob with power off switch4. HIGH EFFICIENCY: The advantage of using pulse width modulation method for dimming or speed regulation is that the energy of the power supply can be fully utilized, and the circuit efficiency is very high5. INSTANTANEOUS CURRENT PROTECTION: Handles the maximum instantaneous current of up to 20A for safe operationSpecification:Item Type: PWM DC Motor GovernorInput Voltage: DC10V-60VOutput Voltage: Linear under loadSpeed Regulation Type: Flow regulationSpeed Regulation Method: Potentiometer(linear)Control Frequency: 25KHZApplicable Current: Continuous operation within 10A, instant current maximum 20AAdjustment Range: 5%-100 percent.Package List:1 x PWM DC Motor GovernorNote:The motor cannot be used in electric vehicles.
