Why Choose the Unitronics UMI-S0028 EMC Input Filter?
The Unitronics UMI-S0028 is a heavy-duty EMC C2 input filter designed to reduce electromagnetic interference generated by industrial variable frequency drives (VFDs). Installed between the mains supply and the inverter input, the filter suppresses conducted electrical noise and helps automation systems comply with IEC / EN 61800-3 electromagnetic compatibility standards.
The filter is engineered for use with Unitronics B1 and B5 series variable frequency drives operating on three-phase 380 V AC power systems. With a 150 A rated current, it supports drives covering a wide power range from approximately 5 kW to 75 kW, making it suitable for high-power motor control systems in industrial automation and manufacturing environments.
By reducing inverter switching noise, the UMI-S0028 protects nearby electronics such as PLCs, sensors and communication networks from interference. This improves system stability and ensures reliable operation of industrial control panels and automation equipment.
