Our General Intelligent Motor Inverter is a high-performance Variable Frequency Drive (VFD) engineered to provide precise speed and torque control for three-phase asynchronous motors. Available in a versatile power range from 5.5kW to 18.5kW, this drive is designed to meet the rigorous demands of modern industrial automation.

Utilizing advanced sensorless vector control technology, this inverter delivers high torque even at low speeds, ensuring smooth startups and stable operation for heavy-load machinery. Whether you are optimizing a pumping system for energy efficiency or requiring high-precision control for a CNC spindle, this series offers the reliability and flexibility needed to maximize your operational uptime.

• Advanced Vector Control: Supports both V/f control and sensorless vector control (SVC), providing superior dynamic response and a high starting torque of 150% at 0.5Hz.

• Intelligent Energy Saving: Automatically optimizes the output voltage based on load conditions, significantly reducing electricity consumption in fan and pump applications.

• Built-in PID Controller: Simplifies the setup of closed-loop control systems (pressure, temperature, flow), eliminating the need for external controllers in many automation tasks.

• Robust Protection Suite: Integrated protection against overcurrent, overvoltage, undervoltage, overheating, and phase loss, ensuring the safety of both the drive and the motor.

• Enhanced Thermal Design: Features an independent air-duct design and high-speed cooling fans to maintain stable performance in ambient temperatures up to 50°C.

1. Pumps & Fans: Ideal for HVAC systems and water treatment plants, providing soft-start capabilities and significant energy savings.

2. Textile & Paper Machinery: Maintaining constant tension and high-speed stability for winding and weaving processes.

3. Conveyor Systems: Managing smooth acceleration and deceleration for heavy-duty material handling in logistics and mining.

4. CNC & Metalworking: Delivering the high-precision speed regulation required for lathes, milling machines, and grinders.

• User-Friendly Interface: Equipped with a detachable digital keypad for easy parameter setting and real-time monitoring of frequency, current, and RPM.

• RS485 Modbus Integration: Easily connects to PLC and SCADA systems for centralized industrial automation and remote diagnostics.

• Compact Modular Design: High power density allows for side-by-side installation in control cabinets, saving valuable panel space.

• Global Standard Compliance: Manufactured under strict ISO9001 quality standards and fully CE certified for international markets.

Q: Can this inverter be used for a single-phase 220V input?

A: This specific series is designed for 3-Phase 380V-480V industrial power. For 220V applications, please refer to our dedicated single-phase to three-phase inverter series.

Q: Does it support remote control?

A: Yes. You can control the drive via the RS485 Modbus port, through the multi-function digital inputs (external switches), or by using an external potentiometer.

Q: How do I select the right power rating?

A: For standard loads (fans/pumps), match the kW rating to your motor. For heavy-duty loads (extruders/crushers), we recommend selecting an inverter one size larger than the motor to handle high starting torque.
