Product Highlights
The ENMod system is a new AC front-end solution for compliance to electromagnetic compatibility (EMC) standards. It consists of the MiniHAM passive harmonic attenuation module and the FARM3 autoranging AC-DC front-end module. Combined with the filtering and hold-up capacitors as specified herein, the ENMod 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
   EN61000-3-3 Inrush Current

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 at up to 600 W of input power at 230 Vac.
The 115/230 Vac input FARM3 is a new member of Vicor’s filter and autoranging module product line that has been optimized for use as the front-end for the MiniHAM. Both modules are in Vicor’s standard Mini half-brick package. Together with Vicor’s 300 V input DC-DC converters, they form the basis of a low noise, high efficiency, rugged, simple and reliable EN compliant power system.
