## Description

Finely controls the speed of DC motors via PWM, ideal for industrial applications and technical projects. Operates at 10-50VDC, offers up to 40A peak and up to 2000W at 50V, has a 50K potentiometer with minimum cut-off, protective housing and screw connectors for power and motor, adjustment from 5 to 100% at 12kHz.
For controlling the speed of DC motors using the Pulse Modulation (PWM) method. It comes with a protective case and can control a motor with a maximum power of 2000W at 50V. We do not recommend using the module at over 1000W continuously unless it is possible to maintain the module at an acceptable working temperature. Its overheating will inevitably lead to its burning.
The module has 4 screw connectors: plus and minus power source between 10 and 50VDC, plus and minus controlled motor. The input voltage will be the operating voltage of the motor.
THERE IS NO POLARITY PROTECTION! CONNECT THE POWER SUPPLY CORRECTLY.
The potentiometer used is a 50K one with a click (at minimum it breaks).
