Why Choose the Unitronics UMI-S0039 EMC Output Filter?
The Unitronics UMI-S0039 is a heavy-duty 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.
Designed for three-phase drive systems operating around 380 V AC, the UMI-S0039 supports drives rated approximately 18.5 kW (25 HP) and provides a 100 A rated current. It is typically used with Unitronics B1 and B5 series variable frequency drives to minimise inverter emissions and maintain reliable operation in industrial control systems.
By filtering inverter switching noise before it reaches motor cables, the UMI-S0039 helps prevent interference affecting PLCs, sensors and communication networks. This improves system stability and protects sensitive electronics within industrial control panels and automation installations.
