The VOF-300 series, available in open-frame and enclosed metal housings, is a higher-power addition to CUI's portfolio of general-purpose AC-DC power supplies, which currently ranges from 6W to 280W. Offering an ideal combination of economy and performance, the single-output power supply series delivers up to 94% efficiency and as low as 0.3W no-load power consumption for energy-intensive ITE, industrial, and consumer electronics applications.

The open-frame VOF-300 and VOF-300-CNF series offer a wide universal input voltage range of 90 to 264 Vac with output voltage options of 12, 24, 36, and 48 Vdc. All models are UL/cUL and TUV 60950-1 certified, meeting Class B and FCC Class B limits for radiated emissions under EN 55032. The series has a minimum MTBF of 160,000 hours at 115 Vac and 25°C ambient temperature, calculated per MIL-HDBK-217F. Overcurrent, overtemperature, overvoltage, and short-circuit protections are included, as well as power factor correction.

The open version of the VOF-300 series measures 76.2 x 127 x 35.1 mm (3.00 x 5.00 x 1.38 inches) and offers a full-load operating temperature range of -40 to +50°C with forced air ventilation, reducing to +70°C at 60% load. The dimensions for the closed metal enclosure are slightly larger at 88 x 136 x 40.4 mm (3.46 x 5.35 x 1.59 inches), with a full-load operating temperature range of -40 to +60°C with forced air ventilation, and +80°C at 60% load.
