The Mean Well USA USP-350-24 is an open-frame AC/DC power supply designed for ITE (Commercial) applications. It provides a stable 24V output at a rated current of 14.6A, delivering up to 300W of power under free air convection, and 350W with forced air.
This converter operates with a universal AC input range of 90-264VAC and features a built-in active Power Factor Correction (PFC) circuit compliant with EN61000-3-2. Key electrical specifications include a typical efficiency of 88%, line regulation of ±0.5%, and load regulation of ±1.0%. It offers overload protection via constant current limiting and over-voltage protection that shuts down the output.
The USP-350-24 has a compact U-bracket design with dimensions of 235.2mm x 101.5mm x 38.0mm, suitable for chassis mounting. It operates within a wide temperature range of -10°C to 65°C (with derating) and has an MTBF of 106.3K hours at 25°C.
Compliance includes UL60950-1, TUV EN60950-1, and EAC TP TC 004 safety standards, along with EMC compliance to EN55032 Class B and immunity compliance to EN61000-4 series. It is rated RoHS3 Compliant, MSL 1, and REACH Unaffected.
