PRELIMINARY 45 Features Harmonic Current Attenuation to EN61000-3-2 EMI Filtering to EN55022, Level B Transient Immunity to EN61000-4-5 575W Rated Power Output Autoranging 115/230Vac Input Microprocessor Control Inrush Current Limiting Data Sheet ENMods TM Component Power Front End System for EN Compliance Product Highlights The ENMods system is a new AC front end solution for compliance to electromagnetic compatibility (EMC) standards. It consists of the MiniHAM — a passive harmonic attenuation module and the FARM3 — an auto ranging AC-DC front end module. Combined with the filtering and hold-up capacitors as specified herein, the ENMods system provides full compliance to: EN61000-3-2 Harmonic Current EN55022, Level B Conducted Emissions EN61000-4-5 Surge Immunity EN61000-4-11 Line Disturbances The MiniHAM is the first passive product specifically designed for compliance to EN harmonic current limits. Unlike active PFC solutions, the MiniHAM generates no EMI, greatly simplifying and reducing system noise filtering requirements. It is also considerably smaller and more efficient than active alternatives and improves MTBF by an order of magnitude. Optimized for operation on the DC bus (provided by the FARM3) rather than directly on the AC line, it will provide harmonic current compliance up to 600W of input power at 230Vac. The 115/230Vac input FARM3 is a new member of Vicor’s Filter and Autoranging Module product line that has been optimized for use as the...
