CUI Inc today announced the expansion of its VOF open frame ac-dc power supply family with the introduction of 185, 225 and 280 W models. The VOF‑185, VOF‑225 and VOF‑280 series are higher-power additions to CUI’s latest-generation open frame ac-dc power portfolio ranging from 6 to 150 W. Designed to offer a combination of economy and performance in a compact, industry standard 3” x 5” footprint, the single output power supplies deliver efficiencies up to 91% and no-load power consumption as low as 0.5 W at 230 Vac for energy-conscious ITE, industrial and consumer electronics applications.

The three new VOF series feature a wide universal input voltage range of 90 to 277 Vac and offer output voltage options of 12, 15, 24, 36 and 48 Vdc.  All models provide an operating temperature range at full load from -20 up to +50°C with forced air cooling, derating to 50% load at +70°C.  The new power supply family also carries UL/cUL and TUV 60950-1 safety certifications while meeting EN 55022 Class B and FCC Class B limits for radiated emissions.

The series has an MTBF of 250,000 hours minimum at full load at 25°C ambient, calculated per MIL-HDBK-217F. Protections for over voltage, over current and short circuit are included as well as 0.98 typical power factor with active PFC.

The VOF-185, VOF-225 and VOF-280 are available immediately with prices starting at $69 per unit at 100 pieces through distribution. Please contact CUI for OEM pricing.
