1、This regulator is integrated designed for more convenient using experience. 2、The motor can be set to slow start/slow stop time, and the start and stop of the motor is smoother. 3、Can set the upper and lower limits of the rotation speed. 4、Can set the motor acceleration and deceleration amplitude. 5、Wide power supply voltage range and stepless speed adjustment. Features: This regulator is integrated designed for more convenient using experience. The motor can be set to slow start/slow stop time, and the start and stop of the motor is smoother. Can set the upper and lower limits of the rotation speed. Can set the motor acceleration and deceleration amplitude.  Wide power supply voltage range and stepless speed adjustment. Specification: Input Voltage:DC6~60V Output Voltage:Linearity under load Output Current:0~30A Continuous Current:Within 20A Speed Regulation Type:Current Regulation Speed Regulation Mode:Inching + - Speed Regulation Range:0~100% Control Frequency:21KHz Connection Type:Barrier terminal block Supported Motor:Brush Motor Size:96 x 61 x 34mm / 3.78 x 2.4 x 1.34in Panel Opening:92 x 56mm / 3.62 x 2.2in Rotation Speed Digital Display:0~100% Package List: 1 x Speed Regulator Function: Slow start time setting  Function 1: 000 - 100 Slow start to 100% speed time is adjustable between 0-10 seconds, the default is 1 second. Slow stop time setting  Function 2: 000 - 100 The slow stop time is adjustable between 0-10 seconds. The default is 1 second. Lower speed limit setting  Function 3: 000 - 080 The minimum speed is adjustable between 0-80% and less than the maximum speed setting. The default is 0. Speed upper limit setting  Function 4: 000 - 100 The maximum speed is adjustable between 0-100% and is greater than the minimum speed setting. The default is 100%. Acceleration and deceleration value setting  Function 5: 001 002 005 010 015 020 020 025 Each press of the addition and subtraction key speed changes by 1%, 2%, 5%, 10%, 15%, 20%, 25%. Note: The input voltage must be positive or negative. It is not possible to input 220V. The input voltage should be equal to the rated voltage of the motor within 6-60V.
