Lenze E82EV551K2C 8200 Vector Frequency Inverter 0.55 kW

Technical Specifications Breakdown

Key parameters for the E82EV551K2C are listed below for quick reference:

Industry Applications That Cut Costs

The E82EV551K2C suits applications where variable speed control reduces energy consumption and mechanical wear. In conveyor systems, for example, adjusting motor speed to match load demand can lower electricity usage by up to 30% compared to fixed-speed operation. Similarly, in pump and fan applications, the inverter enables soft-start and stop, reducing inrush current and extending equipment life—a direct cost benefit.

For packaging machinery, the vector control capability ensures consistent torque at low speeds, improving product quality and reducing scrap. By integrating this frequency inverter into existing motor systems, facilities can achieve a rapid payback period through reduced maintenance and energy savings.

Installation & Setup Guidance

Proper installation is key to maximizing the E82EV551K2C's performance and longevity. The unit is designed as a built-in device, so ensure adequate ventilation and clearance around the enclosure. Mount the inverter on a flat, vibration-free surface, and follow the manufacturer's wiring diagram for mains and motor connections.

Before power-up, verify that the mains voltage matches the unit's rating—230V, supporting both single-phase and three-phase configurations. Use appropriately sized cables and fuses as per local electrical codes. For DC supply operation, the alternative DC supply range is 140 V - 0% ... 370 V + 0%, allowing flexible integration into DC bus systems.

Maintenance & Reliability

Regular inspection of the inverter's cooling fins and fan (if present) is recommended to prevent dust buildup, which can cause overheating. Check all electrical connections periodically for tightness and signs of corrosion. The unit's power loss of 50 W indicates moderate heat generation, so ensure ambient temperature stays within acceptable limits to avoid derating.

Because the E82EV551K2C includes a brake chopper (data: 90), verify that the braking resistor (if used) is properly rated and connected. A well-maintained inverter can provide years of reliable service, minimizing unplanned downtime.

Cost-Effective Motor Control with the Lenze E82EV551K2C

When production lines demand precise speed control without inflating capital budgets, the Lenze E82EV551K2C delivers a balanced solution. This 8200 Vector Frequency Inverter acts as a base controller for asynchronous motors, offering reliable performance in a compact built-in format. For maintenance teams and OEMs, this unit provides a straightforward path to energy savings and reduced mechanical stress—directly impacting operational ROI.

Compatibility & Integration

The E82EV551K2C is part of the Lenze 8200 series, designed for seamless integration with standard asynchronous motors. Its vector control algorithm ensures precise speed and torque regulation, making it suitable for applications requiring high dynamic response. The unit supports both single-phase and three-phase mains input, offering flexibility in different facility power configurations.

For existing systems, the alternative DC supply capability allows the inverter to be powered from a common DC bus, reducing the need for separate AC supplies and simplifying system architecture.

Selection Guide & Purchasing Advice

When selecting a frequency inverter, consider the motor's rated power, input voltage, and required control features. Its compact design and built-in brake chopper make it a cost-effective choice for new installations or retrofits.

Troubleshooting & Common Issues

If the inverter fails to start, check the mains supply and ensure the control terminals are correctly wired. An overcurrent trip may indicate a motor fault or incorrect parameter settings—review the motor nameplate data and adjust parameters accordingly. If the unit shows a DC bus overvoltage, inspect the braking circuit and ensure the brake chopper is functioning correctly.

For persistent issues, consult the Lenze 8200 series manual for detailed diagnostics. Always disconnect power before performing any maintenance or troubleshooting to ensure safety.
