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

Can I use the RCP-1000-48 for 48V telecom or network power systems?

Yes, it is a strong fit for 48V DC systems because it provides constant voltage output at 48V and 21A. With 1008W available, it is aimed at higher-power 48V infrastructure rather than small control loads.

Is the RCP-1000-48 suitable for 48V industrial or automation equipment?

It can work well where a fixed 48V DC bus is required for industrial electronics or automation subsystems. The rated output is 21A at 48V, giving it more headroom for larger 48V loads within a compact enclosure.

Would this model fit rack-based 48V embedded or communications platforms?

Yes, it is appropriate for rack-style equipment that uses 48V distribution, particularly where serviceability matters. The chassis is 295.0 × 127.0 × 41.0 mm, and the features include hot swap support and output voltage programmability.

Can the RCP-1000-48 be used in scalable multi-supply power systems?

Yes, it supports active current sharing up to 3000W, so it is intended for scalable or redundant power architectures. That can be useful in 48V systems that need modular expansion without changing voltage class.

What is the difference between the RCP-1000-48 and the other listed RCP models?

Within the listed family, the other 1000-class options are RCP-1000-12 at 720W 12V 60A and RCP-1000-24 at 960W 24V 40A. Larger siblings include RCP-1600-12 at 1500W 12V 125A, RCP-1600-24 at 1608W 24V 67A, RCP-1600-48 at 1608W 48V 33.5A, RCP-2000-12 at 1200W 12V 100A, RCP-2000-24 at 1920W 24V 80A, and RCP-2000-48 at 2016W 48V 42A. This model is the 48V, 21A constant-voltage member of the 1000 series set.

Can the RCP-1000-48 be placed in outdoor cabinets?

The operating temperature range is -20°C to +60°C, so the thermal range is broad enough for many equipment environments. No IP rating is included in the provided specs, so the data does not confirm exposed outdoor use or water resistance.
