AC70-T/S2-004G Frequency converter 4 kW In:1-ph/220V | Out:3-ph/220V for 3-phase motors

The Veichi AC70-T/S2-004G frequency converter is designed for controlling three-phase electric motors with a rated power of 4.0 kW at an input supply of 1-ph/220V and output of 3-ph/220V. The device provides stable operation due to its capability of short-circuit current up to 32 A and a maximum output frequency of 400 Hz. The built-in PLC and PID module allow for implementing scalar control mode, linear U/f law and quadratic U/f² law for precise parameter adjustment. Additional features of the vector control mode without an encoder and external control terminal contribute to increasing the reliability and efficiency of the device's operation. This frequency converter is used in industrial automation systems, energy management, and process control. It is effectively used for controlling pumps, compressors, and ventilation systems, ensuring optimal operating modes for electric motors. The device also finds applications in manufacturing workshops, construction, and machine engineering, where precise regulation of electric drives is required. Thanks to a wide range of analog and discrete inputs and outputs, the device integrates into modern monitoring and control systems, facilitating the coordinated operation of complex electronic systems.
