Lenze E82EV303K4B201 Frequency Inverter 30kW

E82EV303K4B201 | Lenze 55A VFD Without Filter

Product Introduction

The Lenze E82EV303K4B201 frequency inverter offers a powerful solution for three-phase motor control. This unit operates without an internal filter, making it suitable for specific industrial setups. It drives a 30kW asynchronous motor with four poles. Additionally, this model handles a mains voltage range from 320V to 550V AC at 45-65 Hz. You can rely on its 55A rated mains current when using a mains choke. Moreover, the output reaches 59A at 8kHz, with a maximum of 89A. Therefore, this inverter supports demanding applications like conveyors, pumps, and fans.

Key Technical Specifications

These figures show the drive’s high capability. For instance, the 89A peak current helps handle heavy starting loads. Furthermore, the wide voltage input adds flexibility for different regional power grids.

Mechanical Dimensions & Environment

The Lenze E82EV303K4B201 has a compact yet rugged enclosure. Its 15kg weight requires a sturdy mounting surface. Meanwhile, the generous cable length allowance simplifies panel layouts. You can place the inverter far from the motor if needed.

Installation Guidelines

First, mount the unit vertically on a non-flammable wall or inside a control cabinet. Next, ensure at least 100mm of free space above and below for cooling airflow. Because the drive loses 810W as heat, proper ventilation is critical. Additionally, use copper cables rated for at least 75°C. Tighten all power terminals to the torque specified in the manual.

For EMC compliance, keep the shielded motor cable under 50 meters. Unshielded cable can run up to 100 meters. However, avoid running control wires next to power cables. Separate them by at least 200mm. Finally, connect a suitable mains choke externally, since this model has no internal filter.

Why Choose This Frequency Inverter?

This drive belongs to Lenze’s proven 8200 vector series. It provides precise speed regulation and high overload capacity. Many engineers prefer it for retrofit projects or new machinery. Specifically, the E82EV303K4B201 works well with cranes, extruders, and test stands. Besides, Lenze’s reliable construction reduces unexpected downtime. Therefore, you get a balance of performance and durability.

Frequently Asked Questions (FAQ)

1. Does the Lenze E82EV303K4B201 work without an external mains choke?
Yes, but the rated input current drops without a choke. For full 55A performance, you must add an external mains choke.

2. Can I use this inverter with a single-phase supply?
No. This model requires a three-phase (3/PE AC) supply. Using single-phase will damage the unit.

3. What is the maximum altitude for installation?
Above 1000 meters, you must derate the output current by 1% per 100m. The maximum altitude is 4000 meters.

4. How do I reset a fault on the E82EV303K4B201?
Press the “Reset” button on the keypad or cycle the mains power off for 10 seconds. Check the error code first.

5. Is a braking resistor included?
No. The unit has an internal braking chopper, but you must buy the resistor separately.
