The AA05B DC-DC converter series
is part of Astec's family of advanced
modular power supply components.
Featuring high reliability and small
size, these modules are designed to
reduce product development time and
enhance system performance. The
AA05B offer single and dual outputs
in a compact package. These units
are ideally suited for tele-
communications, industrial, computer
and distributed power system
applications having a widely varying
input voltage.
