Industrial 380V Three Phase VFD Inverter 18KW-90KW Open Loop Vector Control

The NVF2G Series is a high-performance, open-loop vector control inverter designed for heavy-duty industrial applications. Engineered to provide precise speed regulation and high torque at low frequencies, the NVF2G is the go-to solution for large-scale motor control. Whether you are managing high-inertia loads like crushers or variable-torque applications like massive industrial fans, this VFD delivers the stability and efficiency required for modern smart factories.

Supporting a power range from 18.5kW to 315kW, the NVF2G series is built with an industrial-strength architecture. It integrates advanced protection algorithms and multi-function control logic to ensure your high-power motors operate smoothly under fluctuating load conditions.

• High Starting Torque: Features advanced sensorless vector control (SVC) that provides 150% rated torque at 0.5Hz. This ensures reliable startups for heavy machinery under full load without stalling.

• Intelligent Speed Regulation: Offers high-precision speed control with a regulation range of 1:100 (SVC), making it suitable for applications requiring strict speed consistency.

• Dynamic Braking & Rapid Response: Optimized for fast-response environments. The drive manages rapid acceleration and deceleration cycles efficiently, preventing over-voltage trips during high-inertia braking.

• Grid Adaptability: Designed with a wide voltage input range (380V ±15%) and enhanced anti-interference capabilities (EMC), ensuring stable performance even in areas with unstable power grids.

• Multi-Stage Protection Suite: Comprehensive safeguarding including Over-current, Over-voltage, Phase Loss, Overload, Short-circuit, and Over-temperature protection for both the drive and the high-value motor.

1. Mining & Quarrying: Powering heavy-duty crushers, ball mills, and long-distance conveyor belts where high starting torque is non-negotiable.

2. Water & Wastewater: Precision control for high-capacity centrifugal pumps and treatment plant aeration fans.

3. Chemical & Processing: Maintaining constant pressure and speed for large mixers, extruders, and industrial reactors.

4. Metal Fabrication: Speed control for high-power rolling mills, wire drawing machines, and industrial air compressors.

• User-Centric Design: Features a detachable LCD/LED keypad with a parameter copy function, allowing for rapid commissioning of multiple high-power drives across a facility.

• Thermal Reliability: Equipped with high-performance IGBT modules and an optimized cooling channel design to prevent heat buildup during 24/7 continuous operation.

• Flexible I/O Connectivity: Includes 6 digital inputs, 2 analog inputs, and programmable relay outputs, making it easy to interface with any PLC or SCADA architecture.

• Ease of Maintenance: The modular internal structure and accessible terminals allow for quick inspections and cable connections, reducing downtime during routine maintenance.

Q: Can this drive be used for 45kW fan and pump applications?

A: Yes. The NVF2G is a "General Purpose" drive with high overload capacity. While it is built for "Heavy Duty" (G-type) loads, it performs exceptionally well in energy-saving modes for fans and pumps.

Q: Does it support remote monitoring?

A: Absolutely. With the integrated Modbus RS485 interface, you can monitor frequency, current, and fault codes remotely from a control room HMI.

Q: Is it suitable for high-altitude installations?

A: The NVF2G can operate at high altitudes, though derating is required above 1000m. Please consult our technical manual for specific derating curves.
