380V Three Phase VFD Inverter 2.2KW 45KW 55KW 75KW 90KW 110KW 132KW 160KW

The CHINT NVF2G Series is a high-performance, open-loop vector control inverter designed for the precise speed and torque control of three-phase asynchronous motors. Engineered for versatility, this VFD range spans from 2.2kW up to 160kW (and above), making it the ideal choice for heavy-duty industrial applications where reliability and energy savings are paramount.

As a flagship product from CHINT, the NVF2G series combines a compact structural design with superior EMC performance. It features a high starting torque, excellent speed accuracy, and robust motor protection protocols. Whether you are managing industrial fans, heavy-duty conveyors, or precision pump systems, the NVF2G provides the intelligent control necessary to optimize your facility's power consumption.

•    Advanced Vector Control Algorithm: Delivers high torque even at low speeds (150% rated torque at 0.5Hz), ensuring smooth startups for heavy-load machinery.

•    Energy Efficiency & Optimization: Features a built-in energy-saving mode that automatically optimizes the V/F curve based on the load, significantly reducing power costs for centrifugal fans and pumps.

•    High Reliability & Protection: Comprehensive protection suite including overvoltage, undervoltage, overcurrent, overload, and phase loss detection. The PCBA is treated with a specialized conformal coating to resist dust and moisture.

•   Integrated Communication: Supports standard Modbus RTU via RS485 interface, allowing for seamless integration into PLC-controlled automated systems and Building Management Systems (BMS).

•   User-Friendly Interface: Equipped with a detachable digital keypad with a speed control potentiometer, allowing for easy parameter adjustment and real-time monitoring of frequency, current, and voltage.

1. Pumps & Water Treatment: Ideal for constant pressure water supply systems, reducing "water hammer" effects and extending pump lifespan.

2. Fans & Ventilation (HVAC): Precise air volume control for industrial exhaust fans, air conditioning units, and cooling towers.

3. Conveyor & Material Handling: Smooth acceleration and deceleration for belt conveyors, preventing material spillage and mechanical wear.

4. Textile & Plastic Machinery: High-precision speed control for extruders, injection molding machines, and spinning frames.

• Global Certification: Fully CE and RoHS compliant, ensuring the product meets the stringent safety and environmental standards required for international projects.

• Compact Footprint: The modular design allows for side-by-side installation in control cabinets, saving valuable space for panel builders.

• Auto-Tuning Capabilities: Supports both static and dynamic motor parameter auto-tuning, allowing the VFD to match the motor's characteristics perfectly for maximum efficiency.

• Reduced Harmonic Interference: Designed with built-in DC reactors (on higher power models) and optimized EMI filters to minimize interference with sensitive electronic equipment.

Q: What is the difference between "G Type" and "P Type" loads?

A: "G Type" is for General/Constant Torque loads (like conveyors or compressors) requiring higher overload capacity. "P Type" is for Fans/Pumps (Variable Torque) where high starting torque is less critical but energy efficiency is the priority.

Q: Can this VFD be used with a single-phase power supply?

A: The NVF2G series listed here is specifically for Three-Phase 380V input. For single-phase 220V requirements, please consult our NVF3 Series or specific 220V models.

Q: How do I set up the Modbus communication?

A: The NVF2G supports RS485. You can configure the baud rate, parity, and station address via parameters P0.01 and the PD communication parameter group in the manual.
