It is a DC Motor Speed Regulator/PWM Regulator, Working Voltage: DC 9 ~48V, Working Current: 20A, It has small size, high efficiency, long term stable and reliable quality,easy installation and use, Especially Suitable for DC Motor and other equipment etc.

• Working Voltage: DC 9 ~48V (DC Regulated Power Suppy)
• 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

• 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.

• 1 x DC Motor Speed Regulator (PWM Regulator/Motor Controller)
