Product Highlights
From AC line in, to highly regulated DC
out, Vicor offers the total design solution
through a complete family of off-line front
end and DC-DC modular power components.
Vicor’s family of off-line front ends
interface VI-260 and VI-J60 series
DC-DC converters, and MegaMods, to
100, 115, 230 or 240Vac single-phase and
208Vac three-phase mains. In addition,
front ends provide conducted EMI/RFI
filtering to FCC/VDE (Class B singlephase, Class A three-phase), transient
surge protection, active inrush limiting, a
BUS OK status output (suitable for
controlling Vicor DC-DC converter
modules via their Gate In pin) and an AC
OK status output for system use in the
event of loss of the AC line.
