High density Ac-Dc power housed in open frame packages

CUI’s Power Group has announced the addition of 275 W, 350 W, and 550 W models to its VOF family of open frame ac-dc power supplies.

The VOF‑275, VOF‑350, and VOF‑550 series are housed in compact, low profile packages measuring as small as 3 x 5 x 0.75 in (76 x 127 x 19 mm) with high power densities up to 24.4 W/in³. Coupled with high efficiencies up to 94% and no-load power draw as low as 0.5 W, these open frame ac-dc power supplies are ideally suited for IT equipment, industrial, and telecom applications where space and energy consumption are of major concern.

The three new VOF series offer output voltage options from 12 to 58 Vdc and feature wide universal input voltage ranges up to 80 to 264 Vac. Certified to the UL and EN 60950-1 safety standards, the power supplies further meet EN 55032 B requirements for conducted and radiated emissions. All models also provide power factor correction, a 12 Vdc/500 mA fan output, and protections for over voltage, over current, and short circuit.

Operating temperatures range at full load from -40 up to +50°C with forced air cooling, derating to 50% load at +70°C. The high density ac-dc power supplies also carry an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.

CPU choice for display based systems
Behind every display based system is the CPU which acts as the brain of the entire module creating the data that is presented as well as driving the I/O peripherals, display and touchscreen. There are many factors to consider when choosing the right CPU for your project, including whether you pick a complete Single Board Computer (SBC) or a stripped back core module (COM).
