Lenze EVF9326-CVV003 Frequency Inverter 400V AC 11kW

Technical Specifications Breakdown

Key parameters for the EVF9326-CVV003 are listed below for quick reference:

Industry Applications and Cost Benefits

The EVF9326-CVV003 is well-suited for conveyors, pumps, fans, and other variable-torque loads common in manufacturing, material handling, and HVAC systems. With a typical motor power of 11 kW (15 HP), it provides ample headroom for moderate-duty applications. The ability to maintain rated output current at 2, 4, or 8 kHz switching frequencies means you can optimize for noise, efficiency, or motor derating without changing hardware—directly impacting operational costs. By precisely controlling motor speed, this inverter reduces energy consumption compared to fixed-speed starters, offering a clear return on investment through lower electricity bills and reduced mechanical stress on driven equipment.

Installation and Setup Guidance

Mount the cold-plate version on a clean, flat metallic surface to ensure proper heat dissipation. Verify that the incoming AC mains voltage stays within the specified range (320 to 440 VAC) and the frequency between 45 Hz and 65 Hz. Use appropriately rated fuses and cabling for the main circuit current of 20.5 A (with mains choke). Ensure the switching frequency setting matches your motor's thermal capability—23.5 A rated current is available at all three switching frequencies, but always confirm with the motor data plate. For optimal performance, consider using a mains choke as referenced in the specifications.

Maintenance and Reliability Insights

Regularly inspect the cooling surface and ensure airflow is not obstructed. Because this is a cold-plate unit, thermal performance depends on the mounting surface's ability to dissipate heat. Check all power connections for tightness and signs of overheating. The 360 W power loss indicates the heat that must be managed; proper mounting will extend the service life of internal components. Periodically verify that the AC mains voltage remains within 320 to 440 VAC to prevent stress on the input rectifier.

Compatibility and Integration

The EVF9326-CVV003 is designed for use with standard three-phase induction motors. It is part of the Lenze Series 9300 family, ensuring seamless integration with other Series 9300 components. The inverter accepts a wide mains frequency range, making it suitable for installations in different regions. For specific motor and control wiring details, refer to the Lenze documentation for the Series 9300.
