DESCRIPTION
The WRA-YGD-2W & WRB-YGD-2W Series power modules
are low-profile dc-dc converters that operate over input voltage of
4.5-9VDC,9-18VDC,18-36VDC and 36-75VDC
and
±15VDC.
The WRA-YGD-2W & WRB-YGD-2W Series is an excellent for
data
communication
equipments,mobile
power
battery
driven
equipments,distributed
systems,telecommunication
which provide
precisely regulated output voltages of 3.3V,5V,12V,15V,±5V,±12V
equipments,mixed analog/machine control equipments,computer
peripheral systems and industrial robot systems.
The modules have a maximum power rating of 2W and a typical
full-load efficiency of 81%,continuous short circuit,30mV output
ripple,built-in filtering for both input and output minimize the need
for external filtering.
