MPN 19045 — DC Motor Speed Controller Module for 1.8V–15V DC motors. Controls speed via PWM (0–100% duty cycle), 2A continuous output, 30W max power, compact 32×32×15mm form factor.

 

The DC Motor Speed Controller Module (MPN: 19045) is a compact PWM-based speed regulator designed for DC motors operating between 1.8V and 15V DC. Using pulse-width modulation with a fully adjustable duty cycle from 0% to 100%, it allows precise, stepless control of motor speed with minimal energy loss. The built-in self-recovery fuse and power-on LED make it a reliable and beginner-friendly solution for motor control applications.

Key Features

  • Wide Voltage Range (1.8V–15V DC): Compatible with a broad range of small DC motors and power supplies → versatile across many projects
  • PWM Speed Control (0–100% Duty Cycle): Fully adjustable via onboard potentiometer → precise, stepless speed regulation
  • 20kHz PWM Frequency: High-frequency switching reduces audible motor noise → quieter operation
  • 2A Continuous Output Current / 30W Max Power: Handles small to medium DC motors → sufficient for fans, pumps, small drills
  • Self-Recovery Fuse: Protects the circuit from overcurrent automatically → no need to replace fuses manually
  • Ultra-Low Standby Current (7µA): Minimal power draw when idle → energy-efficient in battery-powered setups
  • Compact Size (32×32×15mm): Fits easily into enclosures and project boxes → space-saving design
  • Power-On LED Indicator: Visual confirmation of active power → easy status monitoring

Typical Applications

  • Controlling the speed of small DC motors in DIY robotics and automation projects
  • Fan speed regulation in cooling systems or enclosures
  • Speed control for small pumps in hydroponics or aquarium setups
  • Adjustable lighting (LED dimming) using PWM output
  • Maker and hobbyist projects requiring variable DC load control

FAQ

Q: Can I connect this controller directly to mains AC power (e.g. 220V)?
A: No. This module accepts DC input only (1.8V–15V DC). Connecting it to AC mains will permanently damage the module.

Q: Does polarity matter when wiring the power supply?
A: Yes. Always observe correct polarity on the power input terminals. Reversed polarity may destroy the controller. The motor output terminals can be swapped to reverse motor direction.
