Digital DC Motor PWM Speed Control Switch Governor 12-30V 10A High Efficiency

Description

Item Description:
Applicable voltage: DC12-30V
Working current: 10A
Speed range: 0% -100%
PWM frequency: 15KHz
Speed + digital display + slow start + microcomputer technology, the motor speed from 0% -100% precision speed, at any time shut down and start, more flexible and convenient.
1, digital keys: Keypad than conventional potentiometer speed several advantages, speed precision, long life (1,000,000) does not automatically generate drift is like.
2, digital display: display the value of 001,002,003 ... ... 100, said the maximum motor speed 1%, 2%, 3% ... ... 100%, with the key to use, for precise speed.
3, slow start: This function is very important, slow start, that is, the governor each power, or press the start button, the motor is slowly start to reach the set speed, rather than instantaneous reach the set speed. Which does not produce too much starting current, start the instantaneous impact of damage to power, damage to the motor, damage to the machine and other undesirable phenomena. The traditional governor is connected to the power supply, the motor instantaneous reach the set speed, the above phenomenon inevitably occurs.
4, microcomputer technology: the use of SCM technology than the traditional 555 chip speed is more smooth, good linearity, low noise, long life characteristics, the superiority of the traditional governor immeasurably.
