Test conditions and notes6

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 0.1uf & 47uf 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 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 720mm*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)
6. 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).

FAQ

What heavy-industrial applications can the RSP-1500-12 serve at 1500W?

The RSP-1500-12 delivers 12V at 125A (1500W) and is designed for high-current 12V bus applications such as large automation panels with many actuators, DC motor drive banks, industrial lighting control, and centralized 12V distribution in large machinery. The 90–264VAC input supports worldwide single-phase supplies.

What does the active current sharing (3+1) capability provide for the RSP-1500-12?

Active current sharing allows RSP-1500-12 units to operate in parallel with balanced loads, up to 6000W or (3+1) units. Total output current must not exceed rated current × number of units × 0.9, so three units deliver up to 337.5A at 12V, with a fourth unit providing the +1 redundancy. This suits 12V bus systems that cannot tolerate a single point of failure in the power supply chain.

What is the operating temperature range of the RSP-1500-12?

The RSP-1500-12 operates from -20°C to +70°C ambient, with load derating at higher temperatures according to the derating curve. No IP rating is specified; an appropriate enclosure is required for harsh environments.

What efficiency does the RSP-1500-12 achieve?

The RSP-1500-12 features built-in PFC (power factor 0.98 at 115VAC, 0.95 at 230VAC) and achieves 87% typical efficiency. At the rated 1500W output, this corresponds to approximately 1724W input power and about 224W of heat dissipation, which should be accounted for in enclosure thermal design.
