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
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
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,
extensive control and protection features
for maximum flexibility and provides
low output ripple critical for low voltage telecoms and datacom applications.
