APPLICATIONS
The WRA-ZMD-12W & WRB-ZMD-12W Series series
of DC/DC converters has been designed for a wide range
of applications including communications, industrial
systems and battery powered mobile equipments. Key
features are high power density (12W in a 2“x1“x
0.4“ package) and ultrawide input ranges of 9 – 36 VDC
and 18 –75 VDC. Other features of this converter are
internal filtering according to EN 55022, level A, safety
approval to EN 60950 and UL 1950, wide operating
temperature range and remote on/off (opt.).
