The WPA50 Series is a 50 Watt single
output, low-profile DC-DC converter in
an industry standard package of 2.3” x
0.9” x 0.35” (58.42mm x 22.86mm x
9.0mm). The WPA50 uses unique
proprietary technologies to deliver ultra-
high efficiencies and excellent thermal
performance. It includes extensive
control and protection features for
maximum flexibility and provides a
versatile solution for a whole range of
applications with its input voltage range
of 36-75 VDC and output voltages
between 1.2VDC and 5.0VDC.
The power dissipation of the WPA50
series is so low that a heat sink is not
required. The product features fast
dynamic response characteristics and
low output ripple critical for low voltage
applications. WPA DC-DC converter
modules are certified to UL/CUL 60950,
and VDE to EN60950. It meets CISPR22/
EN55022/FCC15J Class B specs for EMI
levels with external filtering.
This high quality and highly reliable
product is competitively priced and an
ideal solution for distributed power,
telecoms and datacom applications.
