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)
- 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) : Frequency range from 50Hz-1kHz., Frequency range from 240Hz- 13.84kHz., Frequency range from 1.9kHz-100kHz.
- IC board dimension : 3.01 in x 1.83 in.
