Working principle

The KJL6T13B4SN controller consists of a microprocessor and related components. The microprocessor controls various functions and operations in accordance with the control program. It automatically adjusts the output of the thyristor according to the desired motor speed. The multilevel principle is used to change the output voltage of the AC motor by changing the phase difference between two thyristors. In order to accurately and reliably identify the commutation point of the thyristor, an ac commutation/detection circuit is usually provided.

In the closed-loop speed control system, the speed reference signal and the actual motor speed signal are compared, and the deviation signal is sent to the phase lag/sum control circuit. The error signal is amplified and transformed, and the output signal of the converter is used as a parameter to regulate the firing angle of the thyristor SCR. After the control information is sent to the thyristor SCR controlled by the SCR, the voltage output of the motor is adjusted.

Advantages of the KJL6T13B4SN

This product is easy to use and has a wide range of applications. In addition, it has a wide electrical parameter range, and its special voltage characteristics allow high-speed operation under large load.
