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.
