CUI releases 300W AC/DC power supply in compact package
CUI releases 300W AC/DC power supply in compact package: CUI’s Power Group has expanded its VOF AC/DC power supply family, with the introduction of a compact 300W series.
The VOF-300 series is available in open frame and metal enclosed packages, and is a higher-power addition to CUI’s general purpose AC/DC power supply portfolio currently ranging from 6.0 to 280W. According to CUI, the VOF-300 series combines economy and performance in a single output power supply series. It delivers efficiencies up to 94 per cent and no-load power consumption as low as 0.3W, making it particularly suitable for energy-conscious ITE, industrial, and consumer electronics applications.
The open frame VOF-300 and enclosed VOF-300-CNF supplies feature a wide universal input voltage range of 90 to 264V AC with output voltage options of 12, 24, 36, and 48V DC. All models carry UL/cUL and TUV 60950-1 safety certifications and meet EN 55032 Class B and FCC Class B limits for radiated emissions. The supplies have a minimum Mean time between failure (MTBF) of 160,000 hours at 115V AC at 25 degree C ambient, calculated per MIL-HDBK-217F. There is protection for over-current, over-temperature, over-voltage, and short-circuit, as well as power factor correction (PFC).
The open frame version of the VOF-300 series measures 3.00 x 5.00 x 1.38inch (76.2 x 127 x 35.1mm) and provides an operating temperature range at full load from -40 to +50 degree C with forced air cooling, derating to 60 per cent load at +70 degree C. Dimensions for the metal enclosed package measure slightly larger at 3.46 x 5.35 x 1.59inch (88 x 136 x 40.4mm), while carrying an operating temperature range at full load from -40 to +60 degree C with forced air cooling, derating to 60 per cent load at +80 degree C.
The VOF-300 and VOF-300-CNF series are available immediately.
