<h2>Overview</h2>
<p>The Mean Well USP-500-48 is a switching-mode enclosed industrial power supply delivering 504W continuous output at 48V and 10.5A. Designed for industrial automation, control systems, and commercial applications, the USP-500-48 features universal AC input (90–295 VAC) and integrated power factor correction (PFC) for efficient operation across global voltage standards. Its compact, low-profile U-bracket design and fanless construction make it ideal for cabinet mounting in space-constrained environments.</p>
