IMO RFC3-10S single-phase RFI filter for EMC compliance applications, rated at 10 A for 200 to 230 V AC drive and control installations.
The IMO RFC3-10S is a compact and reliable single-phase RFI filter designed to support EMC compliance in industrial control and motor drive applications. Manufactured by IMO Precision Controls, it helps reduce conducted radio frequency interference generated by variable speed drives and other switching power equipment.
Installed between the incoming mains supply and the drive or control equipment, the RFC3-10S helps suppress high frequency electrical noise before it can travel through the supply network. This improves system reliability and helps protect PLCs, sensors, communication devices and other sensitive automation components from interference.
With a 10 A current rating, single-phase 200–230 V AC operation and Category C3 EMC compliance applications, the IMO RFC3-10S is well suited to compact inverter systems, small machinery, control panels and OEM automation equipment.
Variable speed drives and switching power devices can generate high frequency electrical noise during normal operation. The IMO RFC3-10S reduces conducted interference on the supply side, helping maintain stable operation of automation equipment and supporting EMC compliance within industrial installations.
This filter is particularly suitable for control panels where compact drives, PLCs, HMIs and communication equipment are installed close together. By reducing unwanted electrical emissions, it helps minimise disruption and supports dependable machine performance.
