Product Overview

The Heavy-Duty Industrial VFD Series is a high-performance power solution engineered for the most demanding 3-phase motor applications. Ranging from 30kW to 90kW, these drives are built to manage high-inertia loads and provide precise speed regulation in extreme industrial environments.

Utilizing advanced Sensorless Vector Control (SVC), this series delivers exceptional torque at low speeds and maintains tight speed accuracy across varying loads. Whether you are driving heavy-duty mining crushers, large-scale industrial fans, or municipal water pumps, our VFDs ensure soft starts, reduced mechanical wear, and significant energy savings.

Key Technical Advantages

• High-Torque Performance: Delivers up to 150% starting torque at 0.5Hz, making it ideal for heavy-start applications like conveyors, mixers, and extruders.

• Intelligent Thermal Management: Features a high-velocity, dual-fan cooling system and an independent air-duct design to ensure stable operation in ambient temperatures up to 50°C.

• Advanced Protection Suite: 30+ integrated safety features, including protection against over-voltage, phase loss, short-circuits, motor over-temperature, and instantaneous power failure.

• Energy Optimization Logic: Automatically adjusts output based on load demand, specifically optimized for the quadratic torque curves of fans and pumps to maximize electricity savings.

• Robust Hardware Architecture: Built with high-spec IGBT modules and reinforced PCBs with industrial-grade conformal coating to resist humidity, dust, and corrosive vapors.

Why Choose Our High-Power VFDs?

• Smart SCADA Integration: The RS485 Modbus interface allows for seamless connection to PLC systems, enabling remote monitoring of power consumption and real-time diagnostics.

• User-Friendly HMI: Features a detachable digital keypad with a parameter copy function, allowing you to quickly replicate settings across multiple drives.

• Low Harmonic Design: Engineered to minimize electrical noise and interference with sensitive nearby equipment, compliant with international EMC standards.

• Maintenance-Friendly Design: Easy access to cooling fans and capacitors ensures that routine maintenance can be performed with minimal downtime.

FAQ

Q: Can this drive handle a 90kW motor on a 60Hz grid?

A: Yes. Our VFDs are dual-frequency compatible (50Hz/60Hz) and can be easily configured to match local grid standards and motor nameplate requirements.

Q: Is it suitable for constant torque applications?

A: Absolutely. While many drives are only rated for fans and pumps, our Heavy-Duty series is specifically designed for the high-inertia and high-torque demands of industrial machinery.

Q: Do you offer cabinet-mounted versions?

A: We provide the VFD units as standard. However, we can supply complete, pre-wired IP54/IP65 distribution cabinets including breakers and bypass contactors upon request.
