£4,904.20
The Unitronics UMI-1100EU-B7 is a high-power AC variable frequency drive (VFD) designed for precise speed, torque and position control of large three-phase motors in demanding industrial automation applications. As part of the advanced Unitronics UMI-B7 series, it delivers reliable motor control, 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 provide smooth acceleration, stable torque and accurate speed regulation. Its expandable architecture supports communication, encoder and I/O modules, making it suitable for PLC, HMI and industrial network integration.
With a rated output power of 110 kW (150 HP), an approximate output current of 215 A and operation from a three-phase 380–480 V AC supply, the UMI-1100EU-B7 is ideal for high-capacity motors used in pumps, compressors, conveyors, fans and heavy production machinery. Integrated Safe Torque Off (STO) functionality enhances machine safety while reducing system complexity.
Variable frequency drives such as the Unitronics UMI-1100EU-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 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.
