MEAN WELL RSP-320-12 320.4W 1U Metal Enclosed Power Supply (RSP-320-12)

Delivering 320.4W from a compact 1U low-profile metal chassis, the RSP-320-12 is built for high-density industrial and networking environments where space and reliability are critical. Its 12V DC output at up to 26.7A ensures stable power for demanding loads, while the wide 88~264VAC input range makes it globally compatible.

Overview

The MEAN WELL RSP-320-12 is a single-output AC/DC power supply with active PFC and a built-in DC fan for forced air cooling. It operates from -30°C to +70°C with derating above 50°C, and includes full protection against short circuit, overload, over voltage, and over temperature. The metal enclosed design meets 1U height requirements, ideal for rack-mounted equipment, LED lighting, and industrial automation.
