Why Choose the Unitronics UMI-0004BE-B1 Variable Frequency Drive?
The Unitronics UMI-0004BE-B1 is a compact variable frequency drive (VFD) from the UMI-B1 series designed to deliver precise motor speed control, energy efficiency and reliable performance in industrial automation systems. Rated at 0.4 kW (0.5 HP), the drive operates from a single-phase 200–240 V AC supply and provides adjustable frequency output for smooth control of AC motors.
This inverter incorporates advanced motor control technologies such as sensorless vector control (SVC) and space vector PWM to optimise torque performance and maintain stable motor operation across varying load conditions. The drive supports communication via Modbus RTU over RS-485, enabling integration with PLC and HMI systems for modern machine control architectures.
Designed for machine builders and control panel integrators, the UMI-0004BE-B1 provides built-in protection functions, configurable inputs and outputs, and integrated Safe Torque Off (STO) capability to support safe and reliable machine operation.
