Lenze EVF9328-EV – High-Power Frequency Inverter for Demanding Industrial Applications
The Lenze EVF9328-EV is a powerful frequency inverter from the trusted 9300 series, developed to meet the requirements of high-demand motor control applications across various industrial settings. Designed to offer excellent performance, flexible integration, and reliable operation, this inverter is ideal for controlling large AC motors with precision, making it well-suited for complex systems such as material handling equipment, extruders, and heavy-duty conveyor systems.
Rated for 40 HP motor power, the EVF9328-EV delivers substantial output while maintaining efficient and stable performance. It operates with a mains voltage range of 320–440 V AC at a mains frequency of 45–65 Hz, allowing it to work effectively in environments with fluctuating or region-specific power supplies. The inverter is also compatible with alternative DC supply voltages between 460 and 620 V DC, enabling its use in DC link systems or regenerative configurations where energy feedback and optimized power consumption are essential.
The inverter provides a robust power output, supporting 39.5 kVA at 2/4 kHz and 32.6 kVA at 8 kHz, ensuring it can handle motor operations with high dynamic demands. These values make it an excellent choice for applications involving frequent starts, stops, and load variations. It draws 50 amps of mains current when operated with a mains choke or filter, which enhances its electromagnetic compatibility (EMC) and protects upstream power systems from harmonic interference.
To ensure operational longevity and efficiency, the EVF9328-EV dissipates 610 W of power during standard usage. This thermal output requires careful planning for heat management in cabinet installations. Designed for back panel mounting within control cabinets, the inverter fits seamlessly into centralized electrical enclosures, supporting compact and organized control architecture.
As part of Lenze’s versatile 9300 series, the EVF9328-EV supports a wide range of industrial control features. With advanced drive technology, it allows for smooth acceleration and deceleration, accurate torque and speed control, and minimal mechanical stress on connected motors. These features contribute to improved energy efficiency, longer equipment life, and more consistent production outcomes.
The inverter also benefits from Lenze's modular design philosophy, making it easy to integrate with additional modules such as communication interfaces or safety features. Its configuration capabilities allow for user-friendly setup, diagnostic access, and parameter adjustment through software tools, helping technicians reduce commissioning time and improve serviceability.
In conclusion, the Lenze EVF9328-EV frequency inverter stands out as a powerful, flexible, and intelligent drive solution for high-performance industrial systems. Its combination of high output capacity, reliable thermal characteristics, and compatibility with both AC and DC inputs makes it an excellent choice for modern automated machinery that demands precision and efficiency.
