Four low-power, open-frame AC/DC power supply series were added to the VOF product family. The VOF-6B, VOF-10B, VOF-15B, and VOF-20B series are 6-, 10-, 15-, and 20-W additions to the general-purpose AC/DC power supply portfolio that now ranges from 6 to 300 W. The supplies are housed in board-mount packages measuring as small as 1.913 x 0.917 x 0.638 in. The new models feature industry-standard pin-outs, 4-kVac isolation, and no-load power consumption less than 100 mW, making them suitable for space-constrained, low power ITE, industrial, consumer, and smart-home applications.
The 6- to 20-W modules feature universal input voltages from 85 to 264 Vac with single-output voltages of 5, 9, 12, 15, 24, and 48 Vdc, depending upon the series. Operating temperatures at full load range from –25°C up to 50°C, derating to 50% load at 70°C. 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. Protections for short-circuit, overcurrent, and overvoltage come standard. The series also carry a minimum MTBF of 300,000 hours at 115 Vac at 25°C ambient, calculated per MILHDBK-217F.
