Why Choose the Unitronics UMI-S0022 EMC Input Filter?
The Unitronics UMI-S0022 is a high-performance EMC C2 input filter designed to reduce electromagnetic interference generated by variable frequency drives in industrial automation systems. Installed between the power supply and the inverter, the filter suppresses conducted electrical noise and helps installations comply with IEC / EN 61800-3 EMC standards.
The filter is designed for three-phase power systems around 380 V AC and supports drives with power ratings from approximately 0.75 kW to 2.2 kW (1–3 HP). It is commonly used with Unitronics B1-series variable frequency drives to maintain reliable operation and prevent interference with nearby equipment such as PLCs, sensors and communication networks.
By reducing electrical noise produced by inverter switching, the UMI-S0022 improves system stability in industrial control panels and helps automation systems meet EMC compliance requirements in demanding environments.
