Product details

E82EV303K4B302 Lenze 8200 vector Frequency Inverter

The E82EV303K4B302 from Lenze is a built-in vector-controlled frequency inverter in the 8200 vector series. It delivers 30.0 kW for standard 4-pole asynchronous motors in the 400 V class. This model suits demanding industrial drive tasks with reliable torque control and flexible communication.

As a legacy product, the E82EV303K4B302 remains supported by an official migration path to the Lenze i950. You get proven 8200 vector behavior plus a clear route to future upgrades.

Key Advantages

Strong overload capability – 1.8 x rated torque for 60 s. For 15–90 kW units, 2.1 x rated torque for 3 s after controller enable.
Integrated brake chopper – handles generator-mode braking without extra hardware.
Built-in EMC filter – the B302 variant includes a mounted mains filter for cleaner operation.
Flexible communication – RS232/485 system bus plus plug-in fieldbus modules (PROFIBUS DP, CANopen, DeviceNet, INTERBUS, AS-Interface).
Wide output frequency range – 0 to 650 Hz for versatile motor control.
Official Lenze migration support – i950 emulates 8200 vector behavior via PROFIBUS module and L_ICIP library.

Installation Guide

Mount the unit vertically with the heatsink in free air. Keep the IP20 enclosure away from dust and moisture.
Connect 3-phase mains to the supply terminals. Observe the 320–550 V AC range. For DC supply, use 450–775 V DC.
Wire the motor to the output terminals. Use shielded cable for EMC compliance.
Connect the brake resistor to the integrated brake chopper terminals if generator-mode braking is needed.
Plug fieldbus modules into the control interface slots before power-up.
Check the factory-set 8 kHz switching frequency. Adjust to 2/4/16 kHz only if the application requires it.

Commissioning and Maintenance

Set motor parameters through the Lenze keypad or system bus. Match rated current and voltage to the motor nameplate.
Run the auto-tune routine for vector control. This improves low-speed torque accuracy.
Verify the overload settings: 1.8 x for 60 s or 2.1 x for 3 s (15–90 kW).
Keep the heatsink clean. Check fan operation every 6 months in dusty areas.
Store spare units at -25 to +60 °C. Avoid condensation during temperature changes.

Compatibility Notes

Works with standard 4-pole asynchronous motors in the 400 V class.
Supports Lenze system bus devices and plug-in fieldbus modules.
Has an official migration path to the Lenze i950. The i950 emulates 8200 vector behavior via i950 PROFIBUS module and L_ICIP library (Lenze AKB articles 321231/316137).
No drop-in same-order-code replacement exists. Plan migration with Lenze support.

Certifications and Standards

Expert Review

The E82EV303K4B302 is a workhorse for 30 kW drives. Its 1.8 x overload for 60 s handles heavy starts well. The integrated brake chopper saves panel space. The 8200 vector series is legacy, so buyers should note the official i950 migration path. For new designs, the i950 offers a modern route. For existing 8200 vector fleets, this unit keeps lines running with familiar behavior.

Manager’s Insight

This inverter fits retrofit and spare-part roles. The B302 mains filter and built-in brake chopper reduce extra components. The plug-in fieldbus slots let you adapt to PROFIBUS DP, CANopen, or DeviceNet without changing the base unit. Expect 12–24 hour dispatch. Shipping via FedEx, UPS, or DHL keeps downtime short.

Best Applications

Conveyor systems with high starting torque.
Pumps and fans needing 0–650 Hz control.
Material handling equipment with frequent braking.
Retrofit projects for existing 8200 vector installations.
Machinery with PROFIBUS DP, CANopen, or DeviceNet networks.

FAQ

Q: Is the E82EV303K4B302 still available?

A: It is a legacy Lenze product. Official “previous products” support is active. Migration to i950 is available. Check current stock with our team.

Q: Does it include a brake resistor?

A: No. It has an integrated brake transistor (chopper). You must add an external brake resistor for generator-mode braking.

Q: Can I use it with a non-Lenze motor?

A: Yes. It works with standard 4-pole asynchronous motors in the 400 V class. Set motor data to match the nameplate.

Q: What is the overload capacity?

A: 1.8 x rated torque for 60 s. For 15–90 kW units, 2.1 x rated torque for 3 s after controller enable.

Q: Does it support PROFIBUS?

A: Yes. Add a plug-in communication module. Built-in ports cover RS232/485 system bus only.

Q: How do I migrate to the i950?

A: Use the i950 PROFIBUS module and L_ICIP library. Lenze AKB articles 321231/316137 confirm the emulation path.

Q: What is the switching frequency range?

A: 2/4/8/16 kHz selectable. Factory setting is 8 kHz.

Q: What ambient temperature is allowed?

A: -10 to +50 °C. Derate 2.5%/°C above +40 °C. Max. +35 °C ambient when operating at increased rated power.

Q: Does it come with a warranty?

A: Yes. 12-month warranty.

Purchasing Guidance

Confirm your motor power and current before ordering. This unit is rated 30.0 kW / 59.0 A at 8 kHz.
Check whether you need a brake resistor. The chopper is built in, but the resistor is not.
Pick the right fieldbus module for your network. Slots are available for PROFIBUS DP, CANopen, DeviceNet, INTERBUS, and AS-Interface.
For new machines, consider the i950 migration path. For existing 8200 vector lines, this unit is a direct-fit spare.
Verify cabinet space: 350 × 250 × 340 mm and 34.0 kg.
