Bi-directional Forward And Reverse Dc Motor Speed Controller With Digital Display Scale Tachometer

Support motor: DC brush motor Forward and reverse: support Speed range: 0--100% Control frequency: 15KHZ Wiring Type: Terminal Knob specification: 100K (with switch) Wiring Type: Terminal Blocks Motherboard size: 100MM x 76MM x 28MM Shell size: 110x78x38MM Note: The digital display is the motor full speed percentage 0-100, not the actual speed of the motor The input voltage must be divided into positive and negative The input voltage should be to the rated voltage of the motor within 10-55V DC Make that the positive and negative connections are correct powering on, and the wiring should not touch the heat sink, which may burn the circuit board. Note that this is not a power module, and the motor must be connected to adjust the speed. If the motor is not connected, the output of the multimeter will not change, and it cannot be connected to AC. For brushed motors.
