The Unitronics UMI-0055EE-B1 is a powerful and heavy-duty AC variable frequency drive (VFD) designed for precise speed and torque control of three-phase motors in demanding industrial automation and machine building applications. As part of the Unitronics UMI-B1 EU series, this inverter delivers reliable performance, flexible communication and efficient motor control for machinery requiring robust variable speed operation.
This drive combines high-performance VFD operation with an integrated C3 EMC filter, built-in dynamic braking and Safe Torque Off functionality. Its IP20 enclosure and wall or flange mounting format make it suitable for installation inside electrical control panels, machinery cabinets and OEM automation systems.
With a rated output power of 5.5 kW (7.5 HP) and a three-phase 380–440 V AC supply, the UMI-0055EE-B1 is ideal for conveyors, fans, compressors, filling machines, packaging equipment and food production systems requiring dependable variable speed motor control.
Variable frequency drives such as the Unitronics UMI-0055EE-B1 regulate motor speed by adjusting output voltage and frequency. This improves process accuracy, reduces mechanical stress and helps lower energy consumption in motor-driven machinery.
The UMI-B1 EU series is designed for automation environments where compact installation, reliable control and flexible communication are essential. With Modbus RTU, RS-485 connectivity, STO safety functionality, dynamic braking and an integrated EMC filter, this drive can operate as a stand-alone inverter or as part of a PLC-controlled machine system.
