Why Choose the Unitronics UMI-S0033 EMC Output Filter?
The Unitronics UMI-S0033 is a robust EMC C2 output filter designed to reduce electromagnetic interference generated by industrial variable frequency drives (VFDs). Installed between the inverter output and the motor, the filter suppresses high-frequency switching noise and helps automation systems comply with IEC / EN 61800-3 electromagnetic compatibility standards.
The filter is designed for three-phase 380 V AC drive systems and supports drives typically rated between 1.5 kW and 2.2 kW (2–3 HP), commonly used with Unitronics B1 and B5 series variable frequency drives.
By filtering inverter switching noise before it reaches the motor cables, the UMI-S0033 helps prevent interference affecting nearby electronics such as PLCs, sensors and communication equipment. This improves system reliability in industrial control panels and automation machinery.
