Product Details

1DKJ series electric actuatorOverview:

The continuous emergence of electronic components has led to the rapid development of electronic technology, resulting in significant leaps in the functionality and performance of new electronic and power control systems. Traditional analog circuit electric actuators no longer meet the needs of control systems. Innovative intelligent digital electric actuators, with their rich functions, excellent performance, and human-machine interface, have been widely used.

The mechanical design of intelligent digital electric actuators is basically the same as traditional analog electric actuators, forming an intelligent digital electric actuator that combines servo amplifiers and position transmitters to form a new electronic circuit. It completes input and interface technology, adds fault diagnosis, identification, and logical judgment. In terms of performance, software technology and CPU are used to complete adaptive positioning calculation, making positioning errors smaller and control accuracy improved, making up for the shortcomings in mechanical design. The single servo motor control adopts zero crossing trigger thyristor devices, with simple control methods and convenient on-site debugging, improving the reliability of the whole machine operation. Its electrical control characteristics are as follows:
