AC Variable Frequency Drive VFD Inverter 3 Phase Variable Frequency Converter 45KW

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.

• 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.

1. Machine Shops: Powering 3-phase lathes, milling machines, and CNC equipment in residential garages or small workshops.
2. Agriculture: Operating 380V submersible pumps and irrigation systems from a standard 220V rural power line.
3. HVAC & Industrial Fans: Variable speed control for exhaust fans and cooling systems to reduce noise and vibration.
4. Air Compressors: Providing smooth soft-starts to prevent high-current surges that trip household breakers.

• All-in-One Solution: Replaces the need for a phase converter and a transformer, saving you space and reducing wiring complexity.
• User-Friendly Interface: Features a detachable digital display for easy parameter monitoring and a speed control knob for real-time adjustments.
• Industrial Build Quality: High-quality IGBT modules and flame-retardant housing ensure reliable operation in temperatures from -10°C to +40°C.
• Quick Installation: Standard DIN-rail or screw mounting with a clearly labeled terminal block for straightforward DIY or professional wiring.

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.
