Test conditions and notes7

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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. Touch current was measured from primary input to DC output.
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).
7. 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 )

FAQ

Can I use the RPS-65-3.3 to power 3.3V logic boards or embedded controllers?

Yes, this model provides a constant 3.3V output at up to 10A with a total power rating of 33W. It can fit embedded control boards, processor platforms, and other 3.3V electronics that stay within those limits.

Is the RPS-65-3.3 suitable for industrial or medical electronics that need a high-current 3.3V rail?

It can be suitable where a regulated 3.3V supply is required and the load does not exceed 10A or 33W. This unit is medical safety approved and features extremely low leakage current.

Can this power supply run 3.3V FPGA, MCU, or digital interface hardware from AC input?

Yes, for 3.3V digital hardware that fits within the 10A and 33W output rating. The supply accepts 80-264VAC input and converts it to a constant-voltage 3.3V output.

Is the RPS-65-3.3 a good fit for compact instrumentation or control equipment?

It can be a good fit where a compact AC-DC source is needed for a 3.3V rail. The package measures 76.2 x 50.8 x 24.0 mm and weighs 0.11 kg, which helps in space-limited equipment designs.

Can the RPS-65-3.3 be used in outdoor control boxes or washdown areas?

No IP rating is listed for this model, so it is better matched to indoor or protected enclosure use rather than exposed outdoor or washdown environments. Its operating temperature range is -30°C to +70°C.

How does the RPS-65-3.3 compare with other 3.3V RPS models?

In the listed series, the 3.3V options are RPS-30-3.3 at 19.8W and 6A, RPS-45-3.3 at 26.4W and 8A, RPS-60-3.3 at 33W and 10A, RPS-65-3.3 at 33W and 10A, and RPS-75-3.3 at 49.5W and 15A. The RPS-65-3.3 matches the RPS-60-3.3 in 3.3V, 10A, and 33W output, while the RPS-75-3.3 provides higher current and power.
