UMI-B5 UL Variable Frequency Drive

Unitronics VFDs (Variable Frequency Drives) are easy to programme and simple to use:


  • Mounting options: Wall, Flange, Rail
  • Built-in EMC filters and dynamic braking units
  • Modbus RTU fieldbus
  • STO (Safe Torque Off)
  • Sensorless vector speed and torque control
  • Supports Induction and Permanent Magnet Motors
  • Heavy-duty Overload Capacity
  • The VFDs are also UL approved, TÜV-SÜD Safety and CE Certified
