Why Choose the Unitronics UMI-S0021 EMC Input Filter?
The Unitronics UMI-S0021 is an EMC C2 input filter designed to reduce electromagnetic interference generated by industrial variable frequency drives. Installed between the power supply and the drive, the filter suppresses conducted electrical noise and helps automation systems comply with IEC / EN 61800-3 EMC standards.
The filter is specifically designed for Unitronics B1-series variable frequency drives operating on single-phase 200-240 V AC systems. It is suitable for drives rated between 1.5 kW and 2.2 kW (2–3 HP), making it ideal for medium-power motor control applications in industrial automation.
By reducing electrical noise produced by inverter switching, the UMI-S0021 protects nearby equipment such as PLCs, sensors and communication networks from interference while improving overall system reliability in industrial control panels.
