Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Touch current was measured from primary input to DC output.
7. 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).
8. 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-30-3.3 for a 3.3V embedded controller or SBC?

Yes, this model is a constant-voltage 3.3V supply rated for up to 6A and 19.8W. It fits embedded boards, logic controllers, or industrial computing devices that require a regulated 3.3V rail and stay within that current and power limit.

Is the RPS-30-3.3 suitable for powering 3.3V sensors and control electronics in automation equipment?

It can be used for 3.3V automation electronics when the total load does not exceed 6A or 19.8W. That makes it better suited to low-voltage control sections, sensor groups, and embedded monitoring circuits than to higher-power field devices.

Can this power supply be used in medical or laboratory electronics that need a low-voltage DC rail?

Yes, the unit is described as a medical power supply and is medical safety approved. For lab or medical electronics that need 3.3V constant voltage, it provides up to 6A in a compact 76.2 × 50.8 × 24.0 mm package.

Is the RPS-30-3.3 meant for outdoor or washdown environments?

The operating temperature range is -30°C to +70°C, but no IP rating is listed in the provided specs. That means temperature capability is stated, while enclosure sealing against water or dust is not, so outdoor or washdown suitability is not defined by these specs.

How does the RPS-30-3.3 compare with the other RPS-30 models?

Within the RPS-30 group, the sibling outputs are RPS-30-5 at 30W, 5V, 6A; RPS-30-7.5 at 30W, 7.5V, 4A; RPS-30-12 at 30W, 12V, 2.5A; RPS-30-15 at 30W, 15V, 2A; RPS-30-24 at 30W, 24V, 1.25A; and RPS-30-48 at 30W, 48V, 0.625A. The RPS-30-3.3 is the lowest-voltage version and is rated at 19.8W with 3.3V output and 6A current.
