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.
