APPLICATIONS
The WRA-ZMD-20W & WRB-ZMD-20W Series is a
family of high performance 20W DC/DC converter
modules featuring ultra wide 4:1 input voltage ranges in a
ultra compact 2“x1“ low profile package with
industry-standard footprint. A very high efficiency al-lows
an operating temperature range of –40°C to 85°C. Further
standard features include remote On/Off, output voltage
trimming,over voltage protection and short-circuit
protection.
Typical applications for these converters are battery
operated equipment and distributed power architectures
in communication and industrial electronics, everywhere
where isolated, tightly regulated voltages are required.
