IMO RFC3-3S single-phase RFI filter with a 3 A rating for 200 to 230 V AC inverter applications, designed to support EN 61800-3 Category C3 EMC compliance.
£6.58
The IMO RFC3-3S is a compact and dependable single-phase RFI filter designed to minimise conducted electromagnetic interference generated by variable speed drives and other industrial power electronics. Manufactured by IMO Precision Controls, it helps machinery achieve improved EMC performance while supporting compliance with industrial electromagnetic compatibility standards.
Designed for use with compatible IMO iDrive2 variable speed drives, the RFC3-3S mounts directly beneath the inverter and connects using flying leads. This simple installation helps reduce electrical noise that could otherwise interfere with PLCs, sensors, communication equipment and other sensitive automation devices.
With a 3 A current rating, single-phase 200 to 230 V AC operation and compliance with EN 61800-3 Category C3 for industrial environments, the RFC3-3S is ideal for compact machinery, OEM equipment and small motor control applications.
Variable speed drives generate high frequency switching noise during normal operation. The IMO RFC3-3S suppresses conducted emissions before they reach the mains supply, helping improve system reliability and reducing interference with nearby automation equipment.
Its compact design and direct mounting arrangement make it particularly suitable for OEM machinery, industrial control panels and compact automation systems where EMC performance is essential.
