UMI-0450CU-B7 Unitronics | 45 kW 3 Phase 200-240VAC | VSD

Why Choose the Unitronics UMI-0450CU-B7 Variable Frequency Drive?

The Unitronics UMI-0450CU-B7 is a powerful 45 kW variable frequency drive (VFD) engineered to deliver precise speed and torque control for industrial three-phase AC motors. Designed for systems operating on a 200–240 V three-phase supply, this inverter enables efficient motor management across demanding automation applications such as pumps, conveyors, compressors and production machinery.

As part of the advanced UMI-B7 series, the drive combines modern motor control algorithms with flexible automation connectivity. The platform supports SVPWM, sensorless vector control and closed-loop vector control, allowing engineers to achieve smooth acceleration, stable torque delivery and improved energy efficiency in industrial processes.

The drive integrates easily with PLC and HMI systems thanks to built-in Modbus RTU communication via RS-485, while optional expansion cards enable further communication and I/O capabilities. This flexible architecture allows the drive to operate as a standalone inverter or as part of a fully integrated automation solution.
