The Mean Well PS-25-12 is a 25.2 W single-output AC-to-DC switching power supply delivering stable 12 V DC at 2.1 A. Built for industrial and electronic applications requiring reliable power conversion, this enclosed unit accepts universal AC input from 85–264 VAC (47–63 Hz) or 120–370 VDC, making it suitable for global deployment. Typical efficiency reaches 78%, with tight output regulation of ±0.5% (line and load) and ripple/noise below 120 mVp-p. Protection circuitry includes short-circuit, overload, overvoltage, and over-temperature safeguards. Free air convection cooling eliminates the need for active thermal management in space-constrained environments.
