New EMC filters for medical machinery applications
Schaffner has introduced its new FN9274 EMC filters, designed according to Class II medical equipment standard IEC / EN 60601-1
The new filters are said to offer product designers two MOPP (Means of Patient Protection) safety protection "out of the box", thereby eliminating any requirement for further EMC or isolation components. The FN9274 filters have a plastic enclosure for higher dielectric strength insulation. Typical applications cited by Schaffner include general medical devices (MDD), in-vitro diagnostic medical devices (IVDD), intensive care environments, test and measurement and electrical and electronic equipment and audio/video and communication equipment (to IEC/UL 62368-1).
Schaffner's FN9274 filters use C18 inlet receptacles without an earth pin (according to IEC 60320) and are compatible with C17 V-Lock locking power cords to avoid accidental disconnection of power. They are available in 3 mounting configurations: front panel mount, rear panel mount and snap-in fit, and there are two termination styles available for each configuration: fast-on connectors and wire leads for direct connection. They are rated to 4000 Vac, with creepage/clearance of 8mm/5mm and are double insulated. The new FN9274 series complements Schaffner’s existing portfolio of IEC filters which have served the medical industry well for many years. None of Schaffner’s FN92xxB and FN92xxEB IEC filter models add leakage current to medical systems, thus maintaining safety in critical environments.
All new filters from Schaffner are designed for a maximum continuous operating voltage of 250VAC, 50/60Hz and for nominal currents up to 15A. They have worldwide approvals in accordance with ENEC, CQC, UL and CSA and meet the requirements for RoHS and REACH regulation.
