Lenze E82EV302K4C200 VFD Inverter 3KW 400V

Lenze E82EV302K4C200 8200 Vector Drive

Product Introduction

The Lenze E82EV302K4C200 belongs to the 8200 Vector series of VFD inverters. Engineers use this drive for precision motor control in industrial machines. It operates on a 3-phase 400V AC or 500V AC mains supply. This model delivers 3KW of motor power, equivalent to 4 horsepower. Its rated output current reaches 10.5A. Additionally, this version comes without an input filter. Therefore, the Lenze E82EV302K4C200 suits applications where EMC compliance comes from external filtering.

Technical Specifications

Input Power Parameters

The Lenze E82EV302K4C200 requires a 3-phase AC supply. The nominal voltage range covers 400V to 500V AC. This flexibility matches European and Asian industrial grids perfectly. You do not need a step-down or step-up transformer for standard 415V or 480V systems. The frequency range follows the mains input from 45Hz to 65Hz.

Output Power and Current

This vector drive provides a motor power rating of 3KW (4 HP). Its rated output current stands at 10.5A. This current supports most 3KW induction motors at full load. For short-term overloads, the drive can exceed 10.5A briefly. However, continuous operation should stay within the rated current. Otherwise, thermal protection will trigger.

Vector Control Features

The 8200 Vector series uses field-oriented control algorithms. This technology delivers high torque even at near-zero speeds. You can achieve speed regulation accuracy within 0.5% of setpoint. Moreover, the drive auto-tunes to connected motors. This feature optimizes performance without manual parameter entry.

Mechanical and Environmental Data

Dimensions and Weight

The Lenze E82EV302K4C200 measures 337mm in height, 100mm in width, and 60mm in depth. Its mass is only 1.7 kg. This slim profile allows side-by-side mounting in crowded cabinets. One person can easily lift and position the drive during installation.

EMC Filter Status

This specific model comes with no built-in EMC filter. This design choice reduces leakage current to ground. It also prevents nuisance tripping of residual current devices. For CE-marked installations, you must add an external filter. Alternatively, use this drive in a shielded enclosure with proper grounding.

Installation Guidelines

Mechanical Mounting Steps

First, mount the Lenze E82EV302K4C200 vertically on a flat metal plate. Use M4 screws through the four mounting holes. Next, leave 100mm of free space above and below the drive. This clearance ensures proper airflow for cooling. Then, avoid installing the drive directly above heat-generating devices like braking resistors. Finally, tighten all screws to 1.5 Nm of torque.

Electrical Connection Procedure

Connect the 3-phase mains input to terminals L1, L2, and L3. Wire the motor output to terminals U, V, and W. Ground the PE terminal with a short, wide copper cable. For control signals, use shielded cables with the shield grounded at the drive end. Additionally, keep control wiring separate from power cables by at least 100mm.

No-Filter Installation Notes

Since the Lenze E82EV302K4C200 lacks an internal filter, you must take extra EMC precautions. Use shielded motor cables with both ends grounded. Install an external EMC filter on the input side if required. Keep the drive inside a grounded metal cabinet. For most retrofit projects, these steps will satisfy basic EMC requirements.

Frequently Asked Questions (FAQ)

1. Can the Lenze E82EV302K4C200 run a 1.5KW motor?

Yes, you can run a smaller motor without problems. Simply reduce the motor current parameter in the drive settings. The Lenze E82EV302K4C200 will adapt its output accordingly.

2. What is the difference between this model and the standard E82EV302K4C?

The standard model includes an internal EMC filter. The E82EV302K4C200 has no filter. Choose the no-filter version for IT grids or systems with sensitive RCD breakers.

3. How do I perform an auto-tune on this vector drive?

First, ensure the motor is cold and disconnected from any load. Then, set parameter C014 to 1 for static auto-tune. Press the start key. The drive will complete the test in under 30 seconds.

4. Can I use this VFD with a single-phase 400V supply?

No, the Lenze E82EV302K4C200 requires a true 3-phase input. Single-phase operation will cause low DC bus voltage and frequent undervoltage faults.

5. What is the maximum switching frequency for this inverter?

The factory setting uses 8 kHz. You can increase it to 16 kHz for silent motor operation. However, higher switching frequencies reduce the rated output current by 20%. Derate accordingly.
