AC/DC power supply series offer high efficiency in a small package
It has been announced that CUI Power Group has expanded 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 6-280W.
Offering a combination of economy and performance, the single output power supply series delivers efficiencies up to 94% and no-load power consumption as low as 0.3W 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 90-264VAC with output voltage options of 12, 24, 36, and 48VDC.
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 115VAC 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 3x5x1.38” (76.2x127x35.1mm) 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 3.46x5.35x1.59” (88x136x40.4mm), 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.
