1-Channel DC Motor Driver 30 A

Description

Compact power driver capable of driving 1 DC motor with a maximum supply voltage of 25 Vdc and a continuous current of 30 A (80 A peak for 10 seconds). It features reverse polarity protection and a PWM generator that allows operation without a host controller. The motor can simply be controlled with the onboard buttons and speed via potentiometer. It has a terminal block for motor connection, two test buttons, inputs for external control, and status LEDs. It can be used in robotic platforms, pump control, electric fans, conveyor belts, and more. Dimensions (mm): 94×78.
