Power supply MEAN WELL RSP-320-5, 320 W, output 5 V, input 88–264 V, RoHS, 115×215×30 mm

MEAN WELL RSP-320-5 is a 320 W enclosed AC-DC power supply with a single fixed 5 V DC output rated at 60 A. It accepts a wide input voltage range of 88–264 V AC, includes PFC and forced-air cooling, and is built in a 1U low-profile housing measuring 115×215×30 mm. The unit is RoHS compliant and intended for industrial use in control cabinets and equipment where a stable 5 V supply is required.

Advantages

The RSP-320-5 delivers high continuous output current (60 A) from a compact 1U profile, provides power factor correction for improved input performance, and uses forced-air cooling for reliable thermal management under load. Its wide 88–264 V input range allows deployment in diverse AC mains environments, and RoHS compliance meets regulatory material requirements.

Suitable for

• Industrial control cabinets and automation equipment
• Telecommunications and network equipment requiring 5 V DC
• Embedded systems and single-board computers with high current demand
• Environments where compact, rack-friendly 1U height is needed

How to use

Mount the RSP-320-5 inside a control cabinet or equipment chassis with adequate airflow for the forced-air cooling. Connect the AC mains input (88–264 V AC) to the specified input terminals following local electrical codes and ensuring proper grounding. Verify the output wiring to the 5 V DC load and ensure polarity and current capacity are correct. Power up and monitor output voltage; confirm stable 5 V output under expected load conditions.

Recommendations

Install the power supply with sufficient ventilation and avoid obstructing airflow. Use appropriate wiring and protection (fuses or circuit breakers) sized for the 60 A output. For long-term reliability, operate within the specified ambient temperature range and reduce load margin if ambient cooling is limited.
