Always ensure your power supply stays within this range for safe operation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this controller be used as an LED dimmer?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! In addition to controlling DC motor speed, this module functions as a stepless LED dimmer for 12V and 5V LED strips, spotlights, and other compatible DC lighting. Simply connect your LED load to the output terminals and adjust the potentiometer for your desired brightness level.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this PWM controller have overcurrent or short-circuit protection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The module includes built-in reverse polarity protection, overcurrent protection, and a self-recovering (auto-reset) fuse. If an overcurrent event occurs, the fuse trips automatically and resets once the fault is cleared — no replacement fuse needed.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I change the motor's rotation direction?\u003c\/h4\u003e\n\u003cp\u003eA: The motor speed regulator includes a direction-switching feature. If the motor is running in the wrong direction, you can toggle the direction control on the module to reverse rotation without rewiring your motor or power supply.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage range does this PWM motor speed controller support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This PWM DC motor speed controller supports an input voltage range of DC 4.5V to 35V, making it compatible with common supply voltages such as 5V, 12V, 24V, and more.
