Why Choose the Unitronics UMI-S0037 EMC Output Filter?
The Unitronics UMI-S0037 is a high-performance 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 drive systems operating around 380-480 V AC and supports drives typically rated between 15 kW and 18.5 kW (20–25 HP). It is commonly used with Unitronics B1 and B5 series variable frequency drives to reduce inverter emissions and protect nearby electronic equipment.
By filtering inverter switching noise before it reaches motor cables, the UMI-S0037 helps prevent interference affecting PLCs, sensors and communication networks while improving system reliability in industrial control panels and automation machinery.
