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 0.1uf & 47uf parallel capacitor.
3. Under parallel operation of more than one rack connecting together, ripple of the output voltage may be higher than the SPEC at light load condition. It will go back to normal ripple level once the output load is more than 10%.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the static characteristics for more details.
6. Please contact MEANWELL for 320~370VDC application.
7. 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)
8. 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-2000-12 for 12V industrial automation or control systems with high current demand?

Yes, this constant-voltage model delivers 12V at up to 100A with a 1200W power rating, which suits larger 12V industrial control and automation loads. Its 90-264VAC input range also supports use across varied AC supply conditions.

Is the RCP-2000-12 appropriate for embedded, test, or DC bus applications that need a strong 12V source?

It can fit centralized 12V DC platforms that need substantial current capacity, because it provides up to 100A output. Programmable output voltage also helps in systems where the 12V rail needs controlled adjustment within the product's supported range.

Can this power supply be used in modular 12V power systems that may grow over time?

Yes, active current sharing up to 6000W makes it relevant for 12V systems that combine multiple supplies for higher-capacity operation. Hot-swap support also makes it practical for modular systems where uptime and replacement speed matter.

Is the RCP-2000-12 suitable for cold or hot environments, and can it be used outdoors?

The specified operating temperature range is -35°C to +70°C, which is broader than many indoor power supplies. No IP rating is listed in the provided specs, so outdoor suitability is not confirmed by the available product data.

How does the RCP-2000-12 compare with related RCP models?

Among the listed 12V models, RCP-1000-12 is 720W and 60A, RCP-1000-12-C is 1000W and 60A, RCP-1600-12 is 1500W and 125A, RCP-1UT is 3000W and 60A, and RCP-2000-12 is 1200W and 100A. The listed 24V models are RCP-1000-24 at 960W and 40A, RCP-1600-24 at 1608W and 67A, and RCP-2000-24 at 1920W and 80A. The listed 48V models are RCP-1000-48 at 1008W and 21A, RCP-1600-48 at 1608W and 33.5A, and RCP-2000-48 at 2016W and 42A.
