10A PWM DC Motor Speed Controller

10A PWM DC Motor Speed Controller Input supply voltage: 10v – 40vdc, max. Current: 15a, control power: 0.01~400w. Static current: 0.02 a (standby). Pwm duty ratio:10%~100%. Pwm rrequency:13 khz, 1. Connect your dc motor (or dc load) to the motor terminals as indicated. 2. Connect a voltage of 10v-36v dc to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits. 3.
