DC motor speed controller PWM 12-50V 5A (kit)

This is a speed control circuit for a DC motor. Not only the speed of the motor can be controlled but the frequency also adjustable.(due to the application of Plus Width Modulation technique).

Technical Specifications:
- Power supply : 12-50VDC. (jumper selection).
- Load voltage : 12-50VDC./ 5A. max.
- Motor speed (PWM) can be adjusted from 0% to 100%.
- Can be adjusted frequency 3 ranges (jumper selection).
1. Frequency range from 50Hz - 1kHz.
2. Frequency range from 240Hz - 13.84kHz.
3.Frequency range from 1.9kHz - 100kHz.
- IC board dimension : 3.01 in x 1.83 in.
