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.
