45KW 400V three-phase inverter EU UMI-0450EE-B1

45kW Three-Phase Inverter – Precise Drive Control

This advanced Unitronics UMI-0450EE-B1 inverter, with a power of 45kW and a 400V supply, is a reliable solution for controlling induction motors in demanding industrial applications. The device offers extensive configuration options and ensures optimal performance, regardless of the load. It is a versatile component that will work well in both new and modernized systems.

Functionality and operational flexibility

The UMI-B1 inverter supports two control modes: vector and scalar, allowing you to adapt the operating parameters to the specifics of a given device. This makes it possible to precisely regulate the motor speed, ensuring optimal energy efficiency and extending its lifespan. The built-in EMC filter of category C3 minimizes electromagnetic interference, and the optional category C2 filter further increases interference resistance. The ability to separate the control panel (from 4kW) facilitates installation and servicing of the device.

Safety and protection

Safe Torque Off (STO) and comprehensive protection functions against damage related to over/under voltage, current or overheating guarantee safe and reliable system operation. The inverter has a TÜV SÜD safety certificate, confirming its compliance with the highest standards of quality and safety. The built-in DC choke (for models ≥18.5kW) stabilizes the supply voltage, protecting the device against fluctuations in the electrical network.
