Frequency Converters 3 Phase 380V — Industrial Three-Phase Motor Control
A three-phase 380V frequency converter (VFD) is the standard drive type for industrial asynchronous motors. Powered by a standard 380V three-phase supply, these drives cover a wide power range from 0.4 to 500 kW with high conversion efficiency. The Chastotnik.ua catalogue features over 1,100 three-phase VFD models from 8 leading manufacturers for pumps, fans, conveyors, compressors, and machine tools.
How to Choose a 3 Phase 380V Frequency Converter
Selecting a three-phase VFD starts with the motor parameters and load characteristics. Key selection criteria:
- Motor power — the VFD rated power must equal or exceed the motor power. For heavy-duty starts (crushers, presses), select one size up.
- Rated current — the VFD output current must exceed the motor rated current. For fan/pump loads, ND (normal duty) mode is sufficient; for constant torque, select HD (heavy duty) mode.
- Control type — scalar control (V/f) suits pumps and fans, while vector control is required for cranes, elevators, and winding machines demanding precise torque.
- IP protection class — IP20 for panel mounting, IP54/IP66 for dusty or wet environments.
- Built-in features — EMC filter, brake module, PLC controller, communication protocol (Modbus, Profibus, EtherCAT).
