IMO RF29A-1A panel mounted EMC/RFI filter for 200 to 240 V AC single-phase variable speed drive applications with a 29 A current rating and EMC Category C2 compliance.
£30.36
The IMO RF29A-1A is a high quality single-phase EMC/RFI filter designed to minimise conducted electromagnetic interference produced by variable speed drives and other industrial power electronics. Manufactured by IMO Precision Controls, it improves electromagnetic compatibility while helping industrial equipment achieve reliable operation and EMC compliance.
Installed between the mains supply and the inverter, the RF29A-1A significantly reduces high frequency electrical noise that can affect PLCs, communication networks, sensors and sensitive electronic equipment. Its compact panel mounted construction makes it suitable for installation inside electrical control panels and machinery enclosures.
With a 29 A current rating, single-phase 200 to 240 V AC operation and suitability for EMC Category C2 applications, the RF29A-1A is an ideal choice for inverter driven machinery including pumps, fans, conveyors and OEM automation equipment.
Variable speed drives generate switching frequencies that can introduce electrical noise into the power supply. The IMO RF29A-1A attenuates these unwanted emissions, helping improve system reliability, minimise interference and support compliance with applicable EMC requirements.
The filter is well suited to industrial machinery where drives operate alongside PLCs, HMIs, communication equipment and other sensitive electronics. By reducing electrical interference, it helps maintain stable machine operation and dependable automation performance.
