Test conditions and notes5

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 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. 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 )
5. 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 is the RSP-75-27 suited for in embedded or industrial systems?

The RSP-75-27 delivers 27V at 2.8A (75.6W), appropriate for powering small motion control modules, specialty field instruments, and embedded subsystems operating on a 24-28V nominal bus. Its compact 159.0 × 97.0 × 30.0 mm form factor suits screw-mounted panel enclosures.

Can the RSP-75-27 operate in cold indoor environments?

Yes. The RSP-75-27 operates from -25°C to +70°C (with output derating at higher temperatures) at 20-90% RH non-condensing. Safety approvals include UL62368-1, TÜV EN62368-1, EN61558, AS/NZS 62368.1, EAC, CCC, BSMI and BIS.

How does the RSP-75-27 compare to the RSP-75-24 and RSP-75-48?

All three share the 159.0 × 97.0 × 30.0 mm chassis and 85-264VAC input. The RSP-75-24 provides 76.8W at 3.2A, the RSP-75-27 provides 75.6W at 2.8A, and the RSP-75-48 provides 76.8W at 1.6A. Power output is similar; current decreases as voltage increases.

What is the rated output power of the RSP-75-27?

The RSP-75-27 is rated at 75.6W (27V × 2.8A). It weighs 0.44 kg and includes a 3-year warranty. Built-in active PFC is included.
