CUI 300 W Ac-Dc Power Supply Series Offers High Efficiency
CUI’s Power Group announced the expansion of its VOF ac-dc power supply family with the introduction of a compact 300 W series. The VOF-300 series, available in open frame and metal enclosed packages, is a higher-power addition to CUI’s general purpose ac-dc power supply portfolio currently ranging from 6 W to 280 W. Offering an ideal combination of economy and performance, the single output power supply series delivers efficiencies up to 94% and no-load power consumption as low as 0.3 W for energy-conscious ITE, industrial, and consumer electronics applications.
The open frame VOF-300 and enclosed VOF-300-CNF series feature a wide universal input voltage range of 90 to 264 Vac with output voltage options of 12, 24, 36, and 48 Vdc. All models carry UL/cUL and TUV 60950-1 safety certifications while meeting EN 55032 Class B and FCC Class B limits for radiated emissions. The series has a minimum MTBF of 160,000 hours at 115 Vac at 25°C ambient, calculated per MIL-HDBK-217F. Protections for over current, over temperature, over voltage, and short circuit are included as well as power factor correction.
The open frame version of the VOF-300 series measures 3.00 x 5.00 x 1.38 in (76.2 x 127 x 35.1 mm) and provides an operating temperature range at full load from -40 up to +50°C with forced air cooling, derating to 60% load at +70°C. Dimensions for the metal enclosed package measure slightly larger at 3.46 x 5.35 x 1.59 in (88 x 136 x 40.4 mm), while carrying an operating temperature range at full load from -40 up to +60°C with forced air cooling, derating to 60% load at +80°C.
The VOF-300 and VOF-300-CNF series are available immediately with prices starting at $111.50 per unit at 25 pieces through distribution. Please contact CUI for OEM pricing.
