E82EV302_4C Lenze 8200-Series Vector Frequency Inverter 3.0 kW

Product Overview

The E82EV302_4C (E82EV302K4C) is a high-performance vector-controlled frequency inverter within the Lenze 8200-series range, specifically designed for 3.0 kW (4.0 HP) motor applications. Engineered for precision and electrical cleanliness, this drive features integrated interference suppression measures to minimize electromagnetic emissions, making it ideal for environments sensitive to RFI. Supporting a wide mains connection range of 400 to 500 VAC, it delivers a rated current of 7.2 A (up to 9.5 A peak), providing the necessary torque for demanding loads in machinery such as industrial mixers, heavy-duty conveyors, and specialized pumps. Its compact, book-style footprint (24.00 x 14.00 x 10.00 cm) and robust German engineering ensure that the E82EV302_4C provides maximum reliability and efficiency, even as the series moves into its phase-out lifecycle.

Technical Configuration

The E82EV302_4C utilizes an advanced vector control algorithm that allows for high dynamic performance and superior motor speed stability. Unlike standard V/f drives, this vector inverter can maintain full torque even at low frequencies, which is essential for heavy-start applications. The internal architecture includes integrated EMC filters to comply with industrial noise standards without requiring additional external components. For system integration, the 8200-series platform supports modular plug-ins for fieldbus communication (including CAN, PROFIBUS, and DeviceNet) and various I/O expansion modules. The drive's power stage is protected by comprehensive monitoring for short circuits, earth faults, and I2t motor thermal overload, ensuring the longevity of the entire drivetrain.

Technical FAQs

Does the '4C' suffix in the model name signify a specific voltage class?

Yes, in the Lenze 8200-series nomenclature, '4' typically denotes the 400 V / 500 V voltage class. The integrated 'C' indicates that the unit comes equipped with internal interference suppression (EMC filter), reducing the need for external filtering in most industrial installations.

Can the E82EV302_4C handle a 150% overload?

Yes, the 8200-series vector inverters are designed to handle a transient overload of 150% (up to 10.8 A in this model) for 60 seconds. This is particularly useful for applications with high breakaway torque or fluctuating loads.

What software is used to parameterize this drive?

The E82EV302_4C is compatible with Lenze Global Drive Control (GDC) software. Connection requires a 2102 fieldbus module (LECOM-A/B) or an EMZ8201BB keypad for manual on-site parameter adjustment.

Engineering & Installation Guide

• Integrated Filter Grounding: To ensure the integrated interference suppression functions correctly, the inverter must be mounted on a conductive, grounded metal plate. Ensure the mounting screws have a good electrical connection to the plate to provide a low-impedance path for high-frequency noise.

• Motor Cable Shielding: Despite the internal filter, motor cables must be shielded to prevent the cable from acting as an antenna. Ground the shield at both the inverter (using the EMC shield sheet) and the motor housing. Keep the unshielded portion of the wires at the terminals as short as possible.

• Thermal Management: The 2.90 kg unit relies on efficient heat dissipation. Maintain at least 100 mm of vertical clearance above and below the drive. If installing multiple units in a single cabinet, monitor the internal temperature to ensure it does not exceed 45 deg C, or provide forced ventilation to avoid automatic power derating.
