APPLICATIONS
The WRA(B)-ZD-5W 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.
