Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
7. For charging related applications, please consult Mean Well for details.
8. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSP-320-2.5/-3.3/-4/-5/-7.5/-12/-13.5/-15)

FAQ

What can the RSP-320-5 power at 5V in an industrial context?

The RSP-320-5 delivers 5V at 60A (300W), making it suitable for legacy TTL logic systems, single-board computer clusters, and industrial HMI displays requiring a high-current 5V supply. Its 30 mm-high case (215.0 × 115.0 × 30.0 mm) is designed to be built into the final equipment.

What ambient temperature range does the RSP-320-5 support?

The RSP-320-5 operates from -30°C to +70°C, with load derating at higher temperatures per the derating curve. It is a component for installation inside end equipment and holds UL62368-1, TÜV EN62368-1, CCC, BSMI, EAC and AS/NZS 60950.1 approvals.

How does the RSP-320-5 compare to the RSP-320-4 and RSP-320-7.5?

All three share the 215.0 × 115.0 × 30.0 mm chassis and 88-264VAC input. The RSP-320-4 provides 240W at 60A, the RSP-320-5 provides 300W at 60A, and the RSP-320-7.5 provides 300W at 40A. The RSP-320-5 and RSP-320-7.5 share the same total wattage but differ in output voltage and current.

What is the actual rated power of the RSP-320-5?

The RSP-320-5 is rated at 300W (5V × 60A). It includes built-in active PFC and weighs 0.9 kg.
