Feature: 1. VOLTAGE AND CURRENT: Motor governor input voltage range from 10‑60V, output current range from 0‑20A, maximum power is 1200W 2. MAIN APPLICATIONS: DC motor driver can be used for DC brushed motor, LED lights, DC brushed fan regulation 3. 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 switch 4. 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 high 5. INSTANTANEOUS CURRENT PROTECTION: Handles the maximum instantaneous current of up to 20A for safe operation Specification: Item Type: PWM DC Motor Governor Input Voltage: DC10V-60V Output Voltage: Linear under load Speed Regulation Type: Flow regulation Speed Regulation Method: Potentiometer(linear) Control Frequency: 25KHZ Applicable Current: Continuous operation within 10A, instant current maximum 20A Adjustment Range: 5%-100 percent. Package List: 1 x PWM DC Motor Governor Note: The motor cannot be used in electric vehicles.
