Affordable Servo VFD Kit: 380V Input 3-Phase Output, Free Technical Support Included

I. Key Technical

1. Input/Output Characteristics

Single-Phase 220V Input:
- Directly compatible with household/industrial single-phase grids, eliminating the need for additional transformers or phase converters.
- Input voltage range: 220V ±15% (187V-253V), adaptable to grid fluctuations.
Three-Phase Output:
- Output voltage: 0-220V three-phase adjustable (simulated via PWM modulation).
- Frequency range: 0-400Hz, supporting high-speed motors (e.g., spindle motors) and low-speed precision control.

2. Power and Load Adaptation

Power Range: 0.4kW-4kW
- 0.4kW-1.5kW: Suitable for light loads (e.g., small conveyors, fans).
- 2.2kW-4kW: Covers medium-duty equipment (e.g., CNC machines, compressors).
Overload Capacity: Typically 150% rated current for 1 minute to handle short-term heavy loads (e.g., motor startup surges).

3. Control Modes

V/F Control:
- Principle: Maintains a proportional relationship between voltage and frequency, ideal for fan/pump loads.
- Advantage: Simple structure, low cost, and significant energy savings (20%-30% vs. fixed-speed operation).
Sensorless Vector Control (SVC):
- Principle: Decouples motor flux and torque for high torque at low speeds.
- Advantage: Fast dynamic response (≤50ms), suitable for precision machining (e.g., engraving, drilling).

Ⅱ. Core Features

1. Comprehensive Protection Functions

Overcurrent/Overvoltage/Undervoltage Protection: Prevents damage from grid abnormalities or load surges.
Overheating Protection: Built-in temperature sensors safeguard IGBT modules from burnout.
Phase Sequence Error Protection: Automatically detects input phase sequence to prevent motor reversal.
Ground Fault Protection: Isolates insulation failures to ensure operator safety.

User Value: Reduces equipment failure rates, lowering maintenance costs and downtime.

2. Energy Optimization

Soft Start Function: Smoothly accelerates motors, reducing inrush current (50%-70% lower than direct-on-line starting).
Sleep/Wake Mode: Automatically hibernates during idle periods and resumes quickly (e.g., nighttime fan energy savings).

User Value: Long-term electricity cost savings, especially for continuously operating equipment.

3. User-Friendly Design

One-Key Auto-Tuning: Automatically identifies motor parameters (resistance, inductance) to simplify commissioning.
LED/LCD Display: Real-time monitoring of frequency, current, and fault codes for quick troubleshooting.
Multilingual Support: Interfaces available in Chinese/English to lower technical barriers.

User Value: Shortens installation/debugging time and reduces reliance on specialized expertise.

Ⅲ. Typical Application Scenarios and Outcomes

Scenario 1: Retrofitting a Small CNC Machine

Problem: Original fixed-speed motor lacks precision for diverse cutting tools.
Solution:
- Install a 2.2kW servo VFD with vector control mode.
- Use PID regulation to adjust spindle speed dynamically.
Outcome: Surface roughness improved, tool life extended by 30%.

Scenario 2: Agricultural Irrigation Pump Control

Problem: Traditional pumps run at full speed, causing unstable pressure and energy waste.
Solution:
- Pair a 1.5kW VFD with a pressure sensor for constant pressure water supply.
- Enable low-frequency night mode to reduce evaporation.
Outcome: 25% electricity savings, pressure fluctuations reduced from ±15% to ±3%.
