4kW Single-Phase 220V Input 3-Phase 380V Output VFD

It works with most 3-phase AC motors rated 0.4kW to 7.5kW (the most common power range for small industrial equipment and workshop tools). For motors outside this range, contact our team for custom solutions.

No—this VFD is designed to eliminate rewiring. Simply connect the single-phase 220V input to your existing power outlet, and the three-phase 380V output to your motor. Setup takes 15-20 minutes for most users.

Yes. It supports the Modbus RTU communication protocol (via RS485 port) for seamless integration with PLCs, HMIs, or other industrial control systems. It also accepts analog signals (0-10V/4-20mA) for basic remote speed adjustment.

Yes—this is verified by third-party testing. The savings come from matching motor speed to load demand: For example, a fan only needs 50% speed to move half the air, but a fixed-speed motor still uses ~80% of full power. This VFD adjusts speed dynamically, cutting waste.

The standard model has an IP20 rating (protects against solid objects like fingers, not dust/water) — ideal for clean workshops. For dusty/damp areas (e.g., woodworking, food processing), choose the optional IP54 enclosure (protects against dust and low-pressure water splashes).

No expertise is needed! Use the one-key auto-tuning function: The VFD automatically detects your motor’s voltage, current, and frequency specs in 30 seconds. It also has pre-set modes for fan, pump, and machine—just select the mode that matches your use case. For custom settings, contact our support team.

Yes. It’s certified by CE (EU), 3C (China), and TUV (global safety certification)—ensuring it meets safety, EMC (electromagnetic compatibility), and efficiency standards in most countries.

Yes. We offer a 1-year warranty on all VFDs. If you encounter any issues after purchase, please contact our support team for a prompt resolution.

A transformer only converts voltage/phase but can’t control speed—you’ll still have a fixed-speed motor. Our VFD combines phase/voltage conversion AND speed/torque control in one device, plus energy-saving features and safety protections. It’s a all-in-one solution for powering and optimizing 3-phase motors.

The VFD has built-in safeguards:It triggers an **overload alarm** and reduces output power if the motor draws too much current (150% overload for 1 minute).For motor overheating, it works with PT100/PT1000 temperature sensors to shut down temporarily until temperatures return to safe levels—preventing permanent damage.
