Why Choose the Unitronics UMI-S0025 EMC Input Filter?
The Unitronics UMI-S0025 is a high-capacity EMC C2 input filter designed to reduce electromagnetic interference generated by industrial variable frequency drives (VFDs). 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.
The filter is engineered for use with Unitronics B1-series and B5-series drives and supports three-phase installations operating around 380–480 V AC. It is typically used with drives rated approximately 15 kW to 18.5 kW (20–25 HP), making it suitable for high-power motor control applications in industrial automation environments.
By reducing inverter switching noise, the UMI-S0025 protects nearby equipment such as PLCs, sensors and communication networks from interference while improving system stability in industrial control panels and manufacturing machinery.
