DC PWM Motor Speed Controller 1.8V–15V 2A Adjustable Module
DC PWM Motor Speed Controller 1.8V–15V 2A Adjustable Module
DC PWM Motor Speed Controller — Precise, Adjustable Speed Control
Take full command of your DC motor projects with this compact and versatile PWM Motor Speed Controller. Designed for a wide input voltage range of 1.8V to 15V DC and a continuous output current of 2A, this module delivers smooth, reliable speed regulation for motors, fans, pumps, and other DC loads. The fully adjustable duty cycle (0%–100%) lets you dial in exactly the speed you need — from a complete stop to full throttle.
Key Features
- Wide Voltage Compatibility: Works with 1.8V, 3V, 5V, 6V, 12V, and up to 15V DC power supplies.
- Full Duty Cycle Control: Smoothly adjustable from 0% to 100% via the onboard knob for precise speed management.
- 2A Continuous Output Current: Supports a maximum continuous current of 2A and a peak output power of 30W.
- Self-Recovery Fuse: Built-in 2A self-recovery (resettable) fuse protects your circuit from overcurrent events without needing fuse replacement.
- Power-On LED Indicator: Convenient LED light confirms the module is powered and operational at a glance.
- Compact Form Factor: Measures approximately 32 × 32 × 15 mm (1.25" × 1.25" × 0.59") — easy to integrate into tight enclosures and DIY builds.
- Pulse-Width Modulation (PWM) Technology: Delivers efficient, low-heat speed control that prolongs motor life and reduces energy waste.
- Versatile Applications: Ideal for DC motors, LED dimming, small fans, water pumps, and other DC load control projects.

Frequently Asked Questions
Q: What is the maximum voltage and current this PWM motor speed controller supports?
A: This DC PWM motor speed controller supports an input voltage range of 1.8V to 15V DC and a maximum continuous output current of 2A, with a peak output power of 30W. It is suitable for a wide range of low-voltage DC motors and loads.
Q: Can this PWM speed controller be used to dim LEDs or control fans?
A: Yes! In addition to controlling DC motor speed, this adjustable PWM drive module can be used for LED dimming, small fan speed regulation, water pump control, and other DC load applications — anywhere you need variable power output from a DC source.
Q: What does the self-recovery fuse do on this motor speed controller?
A: The built-in 2A self-recovery (resettable) fuse automatically trips and cuts the circuit if the current exceeds 2A, protecting your motor and module from damage. Unlike a standard fuse, it resets itself once the overcurrent condition is removed, so no fuse replacement is needed.
