Compact ac-dc power supplies achieve 87% efficiency

CUI Inc. announces five new series of encapsulated ac-dc power supplies ranging from 5 to 25 W. The compact, board-mount VSK series measures 2 x 1 x 0.6 inches in the 5-W package. With efficiency reaching 87% and an operating temperature range of -25° to 70 °C, these isolated ac-dc modules are suited for use in low power ITE, industrial, and consumer electronics applications where board space is limited.

The VSK series provides continuous output power, universal input (85 to 264 Vac), and is offered in fully regulated dc outputs of 3.3, 5, 9, 12, 15, 24, and 48 Vdc. The class II ac-dc modules carry UL/cUL 60950-1 certifications as well as the CE mark. Protections for over voltage, over temperature, and short circuit conditions are included. Modules offer 4K Vac isolation in the 5 and 10 W versions and 3K Vac isolation in the 15, 20, and 25 W versions.
