3 Phase 380V VFD Inverter

3-phase 380V VFD inverters (variable frequency drives) provide precise speed and torque control for three-phase AC motors by adjusting output frequency and voltage. Reduces energy consumption, eliminates mechanical stress on startup, and enables full variable speed control from 0–400Hz.

Available from 0.75kW to 500kW. V/F control and vector control supported. RS485 Modbus communication standard, optional fieldbus available. Factory-direct supply with OEM and wholesale options.

Key Features

Variable speed control — 0–400Hz frequency range, precise torque and speed adjustment
V/F control and vector control — suitable for general and high-precision applications
Wide input voltage — 220V / 380V / 400V / 415V / 440V / 480V / 660V / 690V (three-phase)
Built-in motor protection — overload, overvoltage, undervoltage, phase failure
RS485 Modbus — remote monitoring and PLC/SCADA integration, optional fieldbus
Overload capacity — 150% for 60s (typical)
Forced air cooling — suitable for continuous industrial operation
OEM and wholesale supply available — factory direct

Applications

Suitable for pumps, fans, compressors, conveyors, HVAC systems, manufacturing equipment, water treatment systems, and industrial automation applications.
