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:

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 front end for the MiniHAM.
Both modules are in Vicor’s standard Mini
half-brick package. Together with Vicor’s
1st or 2nd Generation 300V input DC-DC
converters, they form the basis of a low
noise, high efficiency, rugged, simple and
reliable EN compliant power system.
*EN1 product includes one each MiniHAM and FARM3 with same product grade, pin and baseplate style.
**Pin styles S & N are compatible with the ModuMate interconnect system for socketing and surface mounting.
