The Mean Well PPS-125-15 is a 125W open-frame AC-DC power supply engineered for industrial and embedded system applications. It delivers a single regulated 15VDC output with active Power Factor Correction (PFC) and universal AC input capability spanning 90–264VAC at 47–63Hz. The unit combines fan-assisted and convection cooling to achieve 125W rated output at 8.4A, with automatic protection against overload, overvoltage, and over-temperature faults. Isolation ratings of 3kVAC (input to output) and 1.5kVAC (input to ground) meet safety standards for harsh industrial environments.
