Category
TitleAC/DC CONVERTER 12V 300W
Description

CUI’s 300 W open-frame AC / DC power supplies are higher-power additions to CUI’s latest-generation open-frame AC / DC power portfolio. The VOF-300 series is designed to offer a combination of economy and performance in a compact, industry-standard 3" x 5" footprint. With efficiency up to 94% and no-load power consumption < 0.3 W, these power modules are ideally suited for energy-conscious ITE, industrial, and consumer electronics applications.
