PWM 60W, 5V, 3A

SKU: 8003-06-01

Pulse Width Modulator, 60 Watt

This is a 3 Amp, Pulse Width Modulator (PWM).

PWMs are excellent tools for a variety of applications, including:

  • Driving a DC Motor -- will allow you to vary its speed
  • Robotics -- will allow you to drive your main motor smoothly and precisely
  • LED driver -- will allow you to control light intensity
  • Dimmer for low voltage incandescent lighting (with a little modification)
  • HO Train controller -- will allow you to vary train speed
  • Ultrasonic -- will allow you to vary its speed

The PWM is generated with an 555 Timer Chip.
