CUI provide high density AC/DC power supplies in low profile, open frame packages
CUI’s Power Group has added 275, 350, and 550W 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 as small as 3.0 x 5.0 x 0.75-inch (76 x 127 x 19mm) with high power densities up to 24.4W/in³. Coupled with high efficiencies up to 94 per cent and no-load power draw as low as 0.5W, CUI explains that these open frame AC/DC power supplies are suitable for space constrained IT equipment, industrial, and telecomms applications.
The three VOF series offer output voltage options from 12 to 58V DC and feature universal input voltage ranges up to 80 to 264V AC. 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 12V DC/500mA fan output, and over-voltage, over-current and short circuit protection.
Operating temperatures range at full load from -40 up to +50 degree C with forced air cooling, derating to 50 per cent load at +70 degree C. The high density AC/DC power supplies also carry a MTBF of 3.37million hours, calculated per Telcordia SR-332 Issue 3.
The VOF‑275, VOF‑350, and VOF‑550 series are available from CUI immediately.
