EATS4 series automatic transfer switch, is a integrating switch and logic control system, don’t need additional controller, realize the automatic transfer switch in a mechanical and electrical integration feature. With a detecting voltage, frequency, communication interface, electrical and mechanical interlock function, which can be realized the automatic electric remote emergency manual control.
Operation is controlled by the logic control board and a variety of logic commands to manage the motor, gearbox operation to achieve, motor driven switch spring storage, instantaneous release of acceleration mechanism, fast switching circuit or circuit conversion, through a clear visible state to achieve safe isolation, greatly improving the electrical performance and mechanical properties.
It is Applied IEC60947-1 IEC60947-3 IEC60947-6-1.
