Low-power open-frame AC/DC power supplies housed in compact, board-mount package

CUI’s Power Group announced the addition of four low power, open frame ac-dc power supply series to its VOF product family. The VOF 6B, VOF 10B, VOF 15B, and VOF 20B series are 6, 10, 15, and 20 W power additions to CUI’s general purpose ac-dc power supply portfolio now ranging from 6 W to 300 W. Housed in compact, board mount packages measuring as small as 1.913 x 0.917 x 0.638 in (48.6 x 23.3 x 16.2 mm), the new models feature industry standard pin-outs, 4 kVac isolation and no-load power consumption less than 100 mW, making them ideal for space-constrained, low power ITE, industrial, consumer, and smart home applications.

The 6 W to 20 W modules feature a wide universal input voltage range of 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 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, over current, and over voltage come standard. The series also carry a minimum MTBF of 300,000 hours at 115 Vac at +25°C ambient, calculated per MIL HDBK 217F.
