Prepared for DC 20A motor speed control circuit (mk2) TL494 PWM control IC is used. Integrated IRF1405 N-channel MOSFET output transistors in the two units have the speed setting potentiometer 10k 100k if the frequency setting is adjusted with a 12-volt or 24-volt DC motor can be used. Speed control range TL494 0/100% idle current drawn from power max 20mA. 20 amps also connected to the supply source (battery, etc.). Voltage sensing feature, there is low ..
