PWM 200W, 12V, 10A

SKU: 8001-06-01

Pulse Width Modulator, 200 Watt

This is a state-of-the-art 200 Watt 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 8 Bit, CMOS Microprocessor which generates extremely accurate pulses.
