PWM Bidirectional DC Motor Speed Regulator,6V‑28V 3A 80W,1203BB Main Chip,Alligator Clips for Fast Connection,Mini Motor Control Module

Battery properties: without battery

Power supply: mains powered / hardwired.

Working voltage: 28v and below.

Origin: china

Input dc6-28v voltage range, applicable current within 3a

With switch function and forward and reverse function

Special reminder:

The dc motor speed regulator is connected to the dc power supply. do not connect it directly to the for home 220v ac power supply.

Note that this is not a power module. it must be connected to the motor to adjust the speed. if the motor is not connected, the output will not change when measured by a multimeter.

When connecting the motor, polarity doesn't matter. if the motor's rotation is counter to what you expect, simply swap the wiring to reverse the direction.

Please note:

1. this speed regulator is used for dc brush motors.

2. not suitable for speed regulation of dc brushless motors; nor can it be used as a voltage regulator or voltage stabilizer!
