Ambient temperature: - 10 50 ; Relative humidity: < 90%; Speed control range: 90-1400r/min 50Hz, 90-1700r/min 60Hz Weight: 295 g Cable method: The black wire is the main motor wire, the red and white are the auxiliary capacitor wires, and the 2 blue wires are the speed control feedback wires, the green wire is the ground wire. List of packages: 1 x speed controller Method of use: Turn off the power, connect them according to the connection scheme and make sure the connection is correct. Attach the controller well and set the speed to the lowest "0" to avoid sudden high current and permanent damage when starting the power supply; Then turn on the power and set the speed knob to the desired position. Turn off the power when it is not needed; The regulator is connected to the engine. If the torque or speed proves to be inconsistent with the requirements, adjust the precision adjustment potentiometer on the side of the product To change the direction of the engine, simply replace the jumpers "CCW" and "CW" on the back of the controller. Choose a short COM and CW connection, then the motor will rotate clockwise. Choose a short COM and CCW connection, then the motor will turn left. (When changing direction, do not change direction until the engine stops working completely).
