400W DC PWM Motor Speed Controller allows you to regulate the speed of a DC motor with a Pulse-Width-Modulated (PWM) DC voltage and a Duty Cycle that may be adjusted from 10% to 100%. Your DC motor or other DC load can receive a continuous current of 0-10A at 12V-40V DC from the motor speed controller. Your DC motor or other DC load can receive an 8A continuous current from the motor speed controller. The circuit also incorporates a 10A fuse, as well as a reverse connection of the power supply and an over-voltage protection feature for the control voltage. This speed regulator uses a barrier terminal block as its wiring type. The output voltage is linear under load and features a control frequency of 13kHz.  The BLDC motor cannot be used with this. The controller is not protected against reverse polarity and will be harmed if the supply voltage is connected with the incorrect polarity.
