In the world of industrial automation, having a reliable and versatile frequency inverter can make all the difference in optimizing your machinery's performance. The Lenze E82EV551_4C from the renowned 8200 Vector series is one such solution that combines advanced technology with user-friendly design. Whether you're involved in material handling, process control, or pump and fan applications, this inverter offers a compelling set of features. 

Key Parameters and Technical Data

The Lenze E82EV551_4C is a 0.55 kW frequency inverter designed for three-phase 400V AC power systems. It belongs to Lenze's 8200 Vector series, which covers a wide power range from 0.25 kW to 90 kW, making it suitable for various industrial scales.

This inverter operates with a switch frequency that is typically set at 8 kHz but can be adjusted to 2, 4, or 16 kHz depending on your application requirements. Higher switching frequencies result in smoother current waveforms but may increase interference with other devices. It boasts an output frequency range of -650 Hz to +650 Hz with a fine resolution of 0.02 Hz, allowing for precise motor control.

When it comes to resilience, the E82EV551_4C offers impressive overload capabilities. Like other models in its series, it can handle 180% overload for 60 seconds. For even more demanding scenarios, the series' inverters from 15.0 kW to 90.0 kW can maintain a 210% overload for 3 seconds.

Its speed control is highly accurate, with a speed setting range of 1:50 even without external feedback. The steady-state speed accuracy remains within ±0.5% across the entire load range, with a minimal speed deviation of ±0.1 Hz. For torque control, it provides a torque setting range of 1:10 (between 3-50 Hz) and a rapid torque rise time of approximately 200 ms during sudden load increases.

The inverter operates efficiently within an ambient temperature range of -10°C to +55°C (with derating above 45°C at 2.5%/K) and features an IP20 protection rating. It also includes built-in RFI filters for enhanced electromagnetic compatibility (EMC).
