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 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)
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

Can the RSP-1000-24 supply a 24V DC bus for a large industrial automation system?

Yes. The RSP-1000-24 delivers 24V at 40A (960W), making it appropriate for powering 24V DC distribution buses in large PLCs, motor drives with 24V logic rails, and industrial control panels with multiple 24V loads. The 90–264VAC input provides universal single-phase compatibility.

What redundancy options are available with the RSP-1000-24?

The RSP-1000-24 supports active current sharing (3+1), enabling up to three units in parallel for 120A at 24V with a fourth unit providing N+1 hot-standby redundancy. The active sharing function balances current automatically across units.

How does the RSP-1000-24 compare to the RSP-1000-48 at the two most common industrial voltages?

The RSP-1000-24 outputs 24V at 40A (960W) while the RSP-1000-48 outputs 48V at 21A (1008W). Both use the same 295.0 × 127.0 × 41.0 mm chassis, 90–264VAC input, -20°C to +60°C temperature range, and 5-year warranty. The 48V model delivers slightly higher total wattage at a lower current.

What is the ambient temperature limit for the RSP-1000-24?

The RSP-1000-24 is rated from -20°C to +60°C ambient. The +60°C upper limit means enclosure cooling must be verified for installations in warm climates or high-load conditions. The unit should not be operated in ambient temperatures above +60°C.

What efficiency does the RSP-1000-24 achieve?

The RSP-1000-24 includes built-in active PFC and achieves up to 91% efficiency. At the rated 960W output, this corresponds to approximately 1055W input power, with roughly 95W dissipated as heat. This is significantly more efficient than typical non-PFC designs at comparable power.
