5X DC Motor Speed Controller PWM Controller, 7-70V 30A Adjustable PWM Motor Speed Regulator 12V 24V

Feature Highlights: 1. Wide Voltage Range – Works with 7V to 70V DC power, making it compatible with 12V, 24V, and other common motor voltages. 2. High Current Capacity – Supports up to 30A, providing reliable speed control for brushed DC motors. 3. Simple PWM Speed Adjustment – Just connect the motor and turn the potentiometer to easily adjust the speed. 4. Durable Aluminum Housing – The black and green aluminum heat sink helps with heat dissipation and offers sturdy protection. 5. Easy to Install – No complicated wiring needed; connect directly to the motor and power supply for quick setup. Product Details: This PWM DC motor speed controller lets you smoothly regulate the speed of brushed DC motors. It’s built with a solid aluminum heat sink to keep things cool during operation. Perfect for DIY projects, small machinery, or modifying kids’ toy cars—just remember to connect it correctly to avoid damaging the board. Important Notes: - Always check that the power supply polarity is correct before turning it on. Reverse connection can damage the controller. - This is a speed controller, not a power supply. It must be connected to a motor to work—a multimeter won’t show output changes without a motor attached. - Do not connect to 220V household AC power. It is designed for DC brushed motors only. - For toy car modifications: If the car already has a forward/reverse switch, install this speed controller between the battery and that switch. This ensures proper function and prevents damage. - Keep wires away from the heat sink to avoid short circuits or overheating.
