Products Highlights
The FM48 input filter module enables
designers to meet the conducted
emission limits of EN55022 Level B
and FCC Level B when used with
Vicor's 48 Volt 2nd Generation of
DC-DC converters. FiltMods accept
an input voltage of 36 to 76Vdc with
a transient withstand capability of
100 Vdc for 100 msec. The FiltMods are
packaged in an industry standard
"quarter-brick" module measuring
2.28" x 1.45" x 0.5" and are available
in either 8 or 12 Ampere capacity.
Both versions may be on-board or
in-board mounted for height critical
applications. The FiltMods can be used
with Vicor's IAM48 for transient and
surge protection.
