DESCRIPTION
The FA series is a high-density full brick converter that
incorporates the desired features required in today’s
demanding low voltage bus applications. Its unique dual
interleaved phase-shifted topology minimizes both input
and output noise. When performance, reliability, and low
cost are needed, the FA series delivers.
● Optional Chassis Mount Version Available (See CMFA Series)
