It can handle up to 20A of current, covering a broad range of motors used in fans, pumps, and DIY automation projects.\u003c\/p\u003e\n\u003ch4\u003eQ: How does PWM (Pulse Width Modulation) speed control work?\u003c\/h4\u003e\n\u003cp\u003eA: PWM speed control works by rapidly switching the motor's power on and off at a variable duty cycle. By increasing or decreasing the proportion of \"on\" time, the controller smoothly adjusts the effective voltage delivered to the motor — resulting in stepless, precise speed regulation without the energy loss associated with resistor-based methods.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this controller easy to install for a DIY project?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The controller features clearly labeled screw terminal connections for power input and motor output, making installation straightforward. Simply connect your DC power supply to the input terminals and your motor to the output terminals, then use the adjustment knob to set your desired speed. No battery is included or required — it runs directly from your DC power source.\u003c\/p\u003e\n\u003ch4\u003eQ: What types of motors is this PWM controller suitable for?\u003c\/h4\u003e\n\u003cp\u003eA: This controller is designed for use with DC motors only. It is well-suited for brushed DC motors commonly found in fans, water pumps, conveyor belts, small vehicles, robotics, and various industrial or hobbyist automation applications operating within the 9V–60V, 20A specification range.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage range is this DC motor speed controller compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This PWM speed controller supports a wide input voltage range of DC 9V to 60V, making it compatible with common DC motor systems including 12V, 24V, 48V, and 60V configurations.
