The TEM-2 series is a family of isolated dc/dc converters in a
DIP-24 package. They of fer tight line/ load regulation and 500
VDC I/O-isolation. Standard features include an internal filter to
reduce reflected input ripple current and to guarantee low output
noise. This product series provides a cost effective solution by
many industrial or consumer electronics applications.
