Variable Frequency Drive Inverter 220v 0.4kw-630kw Single Phase To Three Phase

The Single-Phase to Three-Phase VFD Inverter is a specialized power conversion solution designed to bridge the gap between residential power supplies and industrial-grade machinery. It allows users to run a standard 3-phase 220V motor using only a single-phase 220V/230V power source.

Unlike traditional static or rotary phase converters, this VFD provides much more than just phase conversion. It offers full speed control, soft-start capabilities, and comprehensive motor protection. It is the ideal choice for home workshops, small-scale farming, and remote pumping stations where 3-phase utility power is either unavailable or too expensive to install.

• High-Efficiency Phase Conversion: Utilizes advanced PWM (Pulse Width Modulation) technology to synthesize a balanced three-phase output, ensuring your motor runs cool and delivers 100% of its rated torque.

• Soft-Start Technology: Eliminates high inrush currents that can trip residential breakers. The motor ramps up smoothly to speed, protecting your mechanical components (belts, gears, and bearings) from shock.

• Variable Speed Control: Built-in potentiometer and digital interface allow for instantaneous RPM adjustment, enabling precision operation for lathes, mills, and pumps.

• Integrated Motor Protection: Constant monitoring for over-voltage, under-voltage, short-circuits, and motor thermal overloads. It acts as both a phase converter and a high-end protective relay.

• Powerful Starting Torque: Optimized for heavy-start loads, providing the necessary "kick" for compressors and deep-well pumps without stalling.

1. Home & Hobbyist Workshops: Powering 3-phase lathes, milling machines, and CNC routers using standard garage outlets.

2. Agriculture & Irrigation: Running 3-phase submersible water pumps on single-phase rural power lines.

3. Food Processing: Operating commercial mixers, meat grinders, and refrigeration compressors in areas without industrial power.

4. Air Compressors: Managing the high starting torque of heavy-duty shop compressors while providing soft-start to prevent flickering lights.

• Easy "Plug & Play" Setup: Most units are pre-configured for standard motor types. Simply connect your input L/N and output U/V/W terminals to begin operation.

• Silent Operation: Features high-carrier frequency switching (up to 15kHz) to reduce "motor hum," making it suitable for quiet workshop environments.

• Ruggedized PCB: Every unit features an industrial-grade conformal coating to protect internal electronics against moisture, dust, and metallic shavings.

• Space-Saving Design: High power density means our converters fit easily into small wall-mounted control boxes.

Q: Can this VFD convert 220V Single-Phase to 380V Three-Phase?

A: This specific model is a 220V to 220V converter. To run a 380V motor, you must either ensure the motor can be re-wired to "Delta" (220V) or use a step-up transformer in conjunction with the VFD.

Q: What size do I need for a 5HP motor?

A: We recommend selecting a VFD that matches or exceeds your motor’s horsepower. For a 5HP (approx. 3.7kW) motor, our 4kW unit is the perfect match.

Q: Does it work with 60Hz motors?

A: Yes. The VFD is fully programmable for both 50Hz and 60Hz motor nameplate specifications.
