Specifications
T
he SQ Series boast over a
decade of reliable, field proven
service and are the recognized
industry standard for high performance
AC/DC power supplies.
These economy priced units are
packaged to provide the user with
maximum space utilization in PC Board
applications having high density.
Features include MTBF’s of greater
than 150,000 hours, lower case tem-
perature rise (to 18°C cooler) and the
high in-circuit performance. This
higher efficiency results in lower
ambient temperatures and greater
system reliability. Dual output tracking
is standard.
