Specification: Description: Introduction to PWM: The full name of pulse width modulation: Pulse WidthModulator, referred to as PWM. Due to its special properties, it is often used as a dimming or DC motor speed regulation in DC loops. This circuit is a motor controller fabricated using the principle of pulse width modulation PWM. There are two advantages to using this method to control motor speed: It mainly changes the duty cycle of the output square wave so that the average on-time on the load changes from 0-100% to achieve the purpose of adjusting the load brightness/speed. The advantage of using the pulse width modulation PWM method to achieve dimming/speed regulation is that the energy of the power supply can be fully utilized and the efficiency of the circuit is high. For example, when the output is a 50% square wave, the pulse width modulation PWM circuit consumes 50% of the power, which means that almost all of the energy is converted to the load power output. When the common resistance step-down speed regulation is adopted, the power supply must provide more than 71% of the output power of the power supply with a maximum output power of 50%, 21% of which is consumed by the voltage drop and heat consumption of the resistor. The pulse width modulation PWM method can be used to obtain the full supply voltage when the load is working, which is beneficial to overcome the inherent coil resistance of the motor and cause the motor to generate more torque. Feature: The products are equipped with external speed control knobs. Positive and negative control, positive stop products are equipped with positive and negative switches. Using high-quality chips, the filter capacitor uses monolithic capacitors, and the circuit is stable and reliable. The heat sink area used by this governor is more than twice that of similar products on the market, and can meet the needs of 60W-150W motors. The controller uses PWM speed control technology, which has the characteristics of high conversion efficiency, wide speed range and stable performance. The controller uses all imported original semiconductor chips from STMicroelectronics. It is tested by voltage, current and function before leaving the factory. The circuit is stable and reliable. Specification: Input Voltage: 5V-30V DC Wide Range Maximum output power: 150W Maximum continuous current 6A PWM Pulse Width Modulation Range: 0%-100% Size: 73.5x45.5x27mm / 2.9x1.8x1.1inlength x width x height Installation hole center distance: 63.5x36.5mm / 2.5x1.4in Location hole diameter: 3.5mm Weight: 69g / 2.4oz Package list: 1 x Adjustable DC Motor Speed Controller Note: The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. Use and wiring method: Connect the power cord to ensure that the positive and negative switch is in the middle zero position, connect the DC power supply, ensure that the DC power supply voltage range is greater than 5V, less than 30V, to ensure that the power output power meets the motor working needs. The DC power positive and negative terminals are not reversed, otherwise the speed regulation
