Test conditions and notes7
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25β of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1ΞΌF & 47ΞΌF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 0% to 100% rated load.
- 6. 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 360mm*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 βEMI testing of component power supplies.β (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 7. The ambient temperature derating of 3.5β/1000m with fanless models and of 5β/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the RS-35-3.3 to power 3.3V embedded boards or logic-level electronics?
Yes, if the equipment requires a constant 3.3V DC source and the total load stays within 35W and 7A. This makes it relevant for embedded boards, logic rails, and other low-voltage electronics designed around 3.3V.
Is the RS-35-3.3 suitable for FPGA, controller, or processor-based industrial electronics?
It can be used where processor, controller, or FPGA-based electronics need a regulated 3.3V DC input and draw no more than 7A. The wide 88-264VAC input is useful when the finished equipment may be installed in different regions.
Can this model support a 3.3V test bench or embedded development fixture?
Yes, for development fixtures or test benches built around 3.3V DC loads up to 35W. Its compact 99.0 Γ 82.0 Γ 36.0 mm footprint also makes it easier to place in compact electronics assemblies.
Is the RS-35-3.3 appropriate for harsh temperature conditions?
The operating temperature range is -25Β°C to +70Β°C, and the unit is specified to withstand 5G vibration. No IP rating is listed, so temperature tolerance is strong, but it should still be used in protected indoor or enclosed environments.
How does the RS-35-3.3 compare with the other 35W RS outputs?
The 35W RS family includes RS-35-3.3 at 3.3V and 7A, RS-35-5 at 5V and 7A, RS-35-12 at 12V and 3A, RS-35-15 at 15V and 2.4A, RS-35-24 at 24V and 1.5A, and RS-35-48 at 48V and 0.8A. RS-35-3.3 is the lowest-voltage option in that group while remaining in the same 35W class.
