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 minimise design-in time and cost.
