UMI-S0027 Unitronics UMI-B1 37-45kW 3P IN FLT C2
MPN: UMI-S0027
Alt. SKU: UMIS0027
Why Choose the Unitronics UMI-S0027 EMC Input Filter?
The Unitronics UMI-S0027 is a high-capacity EMC C2 input filter designed to minimise electromagnetic interference generated by industrial variable frequency drives. Installed between the mains power supply and the inverter, the filter suppresses conducted electrical noise and helps automation systems comply with IEC / EN 61800-3 electromagnetic compatibility standards.
This filter is engineered for use with Unitronics B1-series and B5-series variable frequency drives operating on three-phase power systems. It is typically used with drives rated around 18.5 kW (25 HP), providing reliable EMC suppression for high-power industrial motor control installations.
By reducing inverter switching noise, the UMI-S0027 protects nearby electronics such as PLCs, sensors and communication networks from electrical interference. This improves system stability and ensures reliable operation in industrial automation panels and machine control systems.
