£3,948.00
The Unitronics UMI-0750EU-B7 is a high-capacity AC variable frequency drive (VFD) designed for precise speed, torque and motor control in demanding industrial automation applications. As part of the advanced Unitronics UMI-B7 series, it provides reliable performance, integrated safety and flexible communication for modern machine-building and process control systems.
This drive supports advanced motor control methods including SVPWM, sensorless vector control and closed-loop vector control, helping deliver smooth acceleration, stable torque and accurate speed regulation. Its expandable architecture allows integration with communication, encoder and I/O modules, making it suitable for PLC, HMI and industrial network applications.
With a rated output power of 75 kW (100 HP), an approximate output current of 150 A and operation from a three-phase 380–480 V AC supply, the UMI-0750EU-B7 is ideal for heavy-duty industrial motors used in pumps, compressors, conveyors, fans and large production machinery. Integrated Safe Torque Off (STO) functionality enhances machine safety while reducing system complexity.
Variable frequency drives such as the Unitronics UMI-0750EU-B7 regulate motor speed by adjusting output voltage and frequency. This allows industrial machinery to operate more efficiently while improving process precision, reducing starting current and lowering mechanical stress on motors and driven equipment.
The UMI-B7 series is designed for industrial automation engineers and machine builders that require powerful motor control, integrated safety and flexible system connectivity. Its communication options and advanced control modes make it suitable for both standalone machine control and fully networked automation systems.
