APPLICATIONS

The WRA(B)-ZD-4W series DC/DC converter

is designed for applications requiring very wide

operating voltage range. Typical applications are

tele- and data communication systems, mobile

battery powered equipments and industrial

process control systems with operation from

different input voltages i.e. 12/24 VDC or 24/48

VDC battery voltages. High efficiency allows

operation up to 75°C without derating. Input

filtering according EN 55022-A and FCC, level A.

Low output ripple minimize design-in time and

cost.
