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-2000-48 for a 48V telecom or network power rack?

Yes, this model is a 48V constant voltage supply rated for 2016W and 42A, which fits high-capacity 48V DC bus applications. That output profile is commonly aligned with telecom, network, and communications racks built around 48V distribution. Its 90-264VAC input also supports broad AC source compatibility.

Is the RCP-2000-48 a good fit for 48V industrial automation systems with higher power demand?

For automation equipment designed around a 48V constant voltage rail, this unit provides up to 2016W and 42A. That makes it relevant where a single 48V source needs to support heavier DC demand than a 1000W or 1600W class unit. The output voltage is programmable as well, which can help in tightly controlled DC bus designs.

Can this model be used in redundant or scalable 48V power shelves?

Yes, the RCP-2000-48 supports active current sharing up to 6000W and also supports hot swap. Those features are useful in 48V rack or shelf systems where power capacity may be expanded or serviced at the module level. The base output of each unit is 2016W at 48V and 42A.

Is the RCP-2000-48 suitable for outdoor use or extreme temperatures?

The operating temperature range is -35°C to +70°C, so the model is specified for wide-temperature operation. No IP rating is provided in the listed specs, so the available data does not confirm outdoor ingress protection. The environmental facts provided here are the temperature range and the absence of a published IP code.

How does the RCP-2000-48 compare with the other RCP family options listed here?

The provided siblings include RCP-1000-12 at 720W 12V 60A, RCP-1000-12-C at 1000W 12V 60A, RCP-1000-24 at 960W 24V 40A, and RCP-1000-48 at 1008W 48V 21A. They also include RCP-1600-12 at 1500W 12V 125A, RCP-1600-24 at 1608W 24V 67A, RCP-1600-48 at 1608W 48V 33.5A, RCP-1UT at 3000W 12V 60A, RCP-2000-12 at 1200W 12V 100A, and RCP-2000-24 at 1920W 24V 80A, while this RCP-2000-48 is 2016W 48V 42A. RCP-1U, RCP-1UI, and RCP-MU are listed as siblings but without power, voltage, or current values in the provided data.
