About DROK DC 9-48V 16KHZ PWM Electric Motor Speed
Parameters: Working Voltage: DC 9-48V (DC Regulated Power Supply) Working Current: 20A (Supports high-speed motor of 25A start-up current) Locked Rotor Current: 30A (Maximum, 5 Seconds) Power of Motor: Supports DC brush motor of 20A working current and less than 500W power to regulate speed Speed Ratio: 0-100% (The lowest means cease and the highest means the maximum speed state) PWM Frequency: 16KHZ Input Voltage of PWM Signal: Only supports frequency conversion PWM signal of 5V input Speed Regulation Method: Use potentiometer to adjust 0-5V voltage or input 0-5V voltage to control signal. The potentiometer has 3 wires, two are control terminal and one is ground terminal. When the motor is on the condition of maximum speed state, the control terminals are 5V level voltage. 0-5V Voltage-control Wiring Method: 0-5V Control signal connects to the middle terminal PWM -5V Input. Control signal ground connects to GND. PWM Signal Input Wiring Method: Positive electric signal connects PWM +5V Input terminal. Negative electric signal connects PWM -5V Input terminal. GND Terminal: Don't need to connect Note: Working voltage can't exceed 48V; Please pay attention to voltage polarity of power supply; Do not connect reversely. Package Included: 1 x DC Motor Speed Regulator
