The VOF-S25B-15 is an open frame AC/DC converter manufactured by CUI Inc., engineered for efficient board-level power supply applications. Rated at 25 watts, this single-output converter provides a 15V DC output capable of delivering up to 1.67A. It operates efficiently at 85% while supporting a wide universal input range of 90 to 264 VAC or 120 to 370 VDC, making it suitable for global deployment across varying mains frequencies.
Designed for robust performance in demanding environments, the unit maintains an operating temperature range from -30°C to 70°C with derating applied. Its compact mechanical footprint measures 50.8mm in length, 27.9mm in width, and 24.9mm in height, facilitating space-constrained designs. The device utilizes a 4-DIP module package with through-hole mounting for secure PCB attachment.
Regulatory compliance is supported by multiple international standards, including IEC 60950-1, IEC 62368-1, CISPR 55024, CISPR 55032 Class A, and IEC 61000 series emissions requirements. Approvals from recognized agencies such as UL, TUV, CB Scheme, EN, IEC, and SIQ ensure adherence to safety and electromagnetic compatibility guidelines.
