The input voltage must match the rated voltage of your DC motor (e.g. use 12V supply for a 12V motor, 36V supply for a 36V motor). This controller operates on DC voltage only — do NOT connect to 220V AC mains power.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1× DC 6-60V 30A PWM Adjustable Motor Speed Controller Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRelated Products You May Like\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/1-percent-better-every-day-motivational-canvas-wall-poster-inspirational-quote\"\u003e\"1% Better Every Day\" Motivational Canvas Poster | Wall Art\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFor general guidance on electrical safety standards and low-voltage device compliance, visit the U.S. Consumer Product Safety Commission (CPSC) or review \u003ca href=\"https:\/\/www.osha.gov\/electrical\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eOSHA Electrical Safety guidelines\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What types of motors is this PWM speed controller compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This DC PWM motor speed controller is designed specifically for brushed DC motors. It supports motors rated within the DC 6V–60V range. Always ensure your power supply voltage matches your motor's rated voltage for safe and optimal operation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this controller for a 12V or 24V motor system?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The controller supports any DC voltage between 6V and 60V, making it compatible with 12V, 24V, 36V, 48V, and 60V brushed DC motor setups. Simply match your input supply voltage to your motor's rated voltage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this PWM controller save my custom settings after power loss?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This module features power-off memory storage. All programmed settings — including soft start\/stop times, speed limits, acceleration steps, and PWM frequency — are automatically saved and retained even after the power is disconnected.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I mount this controller in a panel or enclosure?\u003c\/h4\u003e\n\u003cp\u003eA: This module is designed for embedded panel-mount installation. Cut an opening of 92mm × 56mm in your panel or enclosure and insert the module from the front. The module body measures 96mm × 61mm × 34mm overall.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What PWM frequency range does this controller support, and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: The adjustable PWM frequency range is 1 KHz to 100 KHz (default: 15 KHz). A higher frequency reduces audible motor noise but may generate more heat in some motor types, while a lower frequency is better suited for high-current or high-inductance motors. The wide range lets you fine-tune performance for your specific motor.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What types of motors is this PWM speed controller compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This DC PWM motor speed controller is designed specifically for brushed DC motors.
