Product Overview
The 220V to 380V Step-Up VFD Inverter is a specialized solution designed for workshops, farms, and small businesses that lack access to three-phase industrial power. This high-performance frequency converter takes a standard 220V single-phase input and converts it into a 380V three-phase output, allowing you to run heavy-duty industrial machinery without the massive expense of a utility grid upgrade.
Equipped with advanced Vector Control (SVC), this drive doesn't just change the voltage; it provides precise speed control, energy savings, and comprehensive protection for your motor. It is the perfect "bridge" for operating three-phase lathes, pumps, fans, and compressors on a household or light-commercial power supply.
Key Technical Advantages
- Voltage Boosting Technology: Integrated high-efficiency step-up circuitry converts 220V (Single-Phase) directly to 380V (Three-Phase), eliminating the need for bulky external transformers.
- High Starting Torque: Delivers 150% rated torque at low frequencies (0.5Hz), ensuring that heavy-start machines like air compressors and mixers start smoothly under load.
- Precision Speed Regulation: Features a wide output frequency range (0–600Hz), providing stepless speed control to improve machining accuracy and process efficiency.
- Advanced Motor Protection: Built-in safeguards include Over-voltage, Under-voltage, Over-current, Overload, Short-circuit, and Phase Loss protection to prevent motor burnout.
- Energy Efficiency: By optimizing the motor's power consumption based on real-time load requirements, this VFD can reduce energy costs by up to 30% in fan and pump applications.

FAQ
Q: Can this run a 5HP 380V motor on a 220V household outlet?
A: Yes, provided your 220V circuit has enough amperage to support the load. For a 4kW (5.5HP) motor, we recommend a dedicated 30A-40A breaker on the input side.
Q: Is it a "True" 3-Phase output?
A: Absolutely. It produces a true 120-degree phase shift three-phase output, which is much safer and more efficient for motors than static or rotary phase converters.
Q: Does it come with a manual?
A: Every unit includes a comprehensive English manual covering wiring diagrams, parameter settings, and troubleshooting codes.
