CUI’s Power Group has expanded its VOF AC-DC power supply family with a compact 300 W version.
The VOF-300 series, available in open frame and metal enclosed packages, is a higher-power addition to CUI’s general purpose AC-DC portfolio that ranges from 6W to 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 300mW 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 76 x 127 x 35mm 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.
The metal enclosed package is slightly larger at 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.
