Powerful Functional Capabilities
The VEVOR VFD 3KW 220V inverter is designed to deliver reliable motor control across a wide range of industrial and workshop applications.
Flexible Input and Output Configuration
One of the most important advantages of this unit is its 1 or 3 phase input compatibility combined with 3 phase output. This flexibility allows it to be installed in locations where only single-phase power is available, while still operating a three-phase motor efficiently.
Advanced Control Modes
The inverter supports both V/F control and vector control:
- V/F Control provides a stable voltage-to-frequency ratio, suitable for general-purpose motors.
- Vector Control delivers higher torque at low speeds, improving precision and load-handling capability.
These modes make the drive suitable for applications ranging from light-duty fans to heavy CNC spindles.
Wide Frequency Range
With an output frequency range of 0–1000Hz, this VFD supports high-speed motors commonly used in engraving, trimming, and precision milling operations. This wide range enables fine speed adjustment and precise control over motor performance.
Smart Digital Display and User Interface
The VEVOR CNC variable frequency drive features a user-friendly control panel designed for intuitive operation.
Clear Digital Display
The digital display provides real-time feedback, including:
- Output frequency
- Running status
- Error codes
- Parameter settings
This clear visualization allows operators to monitor motor behavior and diagnose issues quickly.
Detachable Control Panel
The detachable keyboard design allows for remote installation, enabling safer and more convenient operation in control cabinets or CNC enclosures. This feature is especially valuable in professional setups where direct access to the inverter is limited.
RS485 Communication and PID Control
RS485 MODBUS Communication
The built-in RS485 communication port supports standard MODBUS protocol, enabling integration with CNC controllers, PLC systems, and industrial automation networks. This allows centralized control, remote monitoring, and synchronization with other equipment.
PID Closed-Loop Control
The advanced PID control function enables precise regulation of speed, pressure, flow, or tension. With fast response and high stability, PID control is ideal for applications such as:
- Pumps
- Compressors
- Extruders
- Conveyors
- Ventilation systems
This capability enhances efficiency while reducing wear on mechanical components.
Low-Noise and Low-Interference Operation
Noise and electromagnetic interference can significantly affect sensitive CNC equipment. The VEVOR VFD 3KW inverter addresses this with optimized design.
Optimized PWM Control
Advanced PWM control technology minimizes switching noise and improves waveform quality, resulting in smoother motor operation.
Electromagnetic Compatibility Design
The internal layout and circuit optimization reduce electromagnetic interference, protecting nearby electronics and improving system reliability.
Efficient Heat Dissipation
The housing features a porous heat dissipation design, allowing effective airflow between components. Adequate spacing and forced-air cooling reduce thermal stress, extending service life even under continuous operation.
Multiple Protection Mechanisms
Safety and reliability are critical in motor control systems. The VEVOR VFD 3KW 220V includes comprehensive protection features to safeguard both the inverter and the connected motor.
Integrated Protection Systems
| Protection Type | Description |
|---|---|
| Overload Protection | Prevents motor damage under excessive load |
