Meets EN60950
The PT4100鈥?8V series of dc/dc
converters provide up 18 Watts/in
3
of
isolated power in a single low-profile
module. Designed to operate from a
standard 48V telecom bus, these modules
employ switching frequencies of up to
850kHz, planar magnetics, and surface-
mount construction. They are designed
for T
elecom, Industrial, Computer, Medical,
and other distributed power applications
that require input-to-output isolation.
