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 0.1μF & 47μF 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. 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 )
7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
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 RS-100-3.3 for 3.3V logic, FPGA, or processor-heavy embedded hardware?

Yes, it is a constant-voltage 3.3V supply rated for 20A and 66W. That makes it relevant for embedded or digital hardware that needs a high-current 3.3V rail in an enclosed system.

Is the RS-100-3.3 suitable for industrial electronics that run on a 3.3V bus?

It can fit industrial electronics designed for 3.3V constant voltage, as long as the total draw remains within 20A and 66W. Its 88-264VAC input also supports equipment intended for a broad AC input range.

Can this model power multiple 3.3V control or communications boards in one enclosure?

It is suited to grouped 3.3V loads in a protected enclosure when the combined requirement stays within 20A and 66W. The compact 159.0 × 97.0 × 38.0 mm package helps where internal equipment space is tight.

Is the RS-100-3.3 rated for indoor or outdoor conditions?

The listed operating temperature range is -25°C to +70°C, and the features note 5G vibration resistance. No IP rating is provided, so the available specs support protected indoor industrial use rather than direct outdoor exposure.

How does the RS-100-3.3 compare with the other RS-100 models?

The RS-100-3.3 is rated for 66W at 3.3V 20A. Other models in the series include RS-100-5 (80W, 5V 16A), RS-100-12 (102W, 12V 8.5A), RS-100-15 (105W, 15V 7A), RS-100-24 (108W, 24V 4.5A), and RS-100-48 (110.4W, 48V 2.3A).
