Product Information

The ENMods system is a new solution for compliance to EN harmonic

current, EMI, and transient immunity standards. It consists of a passive

harmonic current attenuation module — the MiniHAM — and an auto

ranging AC-DC front-end module — the FARM3. Combined with filtering

and hold-up components as specified herein, the ENMods system provides

full compliance to:

EN61000-3-2 Harmonic Current Content Limits

EN55022, Level B conductional environmental limits

EN61000-4-5 Input Surge Immunity

EN61000-4-11 Line Disturbances

The MiniHAM is the first passive product specifically designed for

compliance to 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.

Uniquely intended to operate on the DC bus provided by the FARM3 rather

than directly on the AC line, it will provide harmonic current compliance at

230Vac input at up to 600W of input power. 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.
