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. 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 230mm*230mm 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 “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
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).

FAQ

Can I use the RS-15-12 for a small 12V sensor or relay circuit in industrial equipment?

Yes, it provides a constant 12V output with up to 1.3A and 15.6W available. That makes it appropriate for lower-power 12V control loads that do not need the higher current of larger 12V models.

Is the RS-15-12 a good fit for compact embedded 12V electronics?

It can be a good fit for embedded 12V devices that stay within 1.3A and 15.6W. Its 62.5 × 51.0 × 28.0 mm dimensions and 0.13 kg weight are useful where board or enclosure space is tight.

Can this model power a small 12V automation accessory or interface board?

Yes, if the accessory requires a regulated 12V constant-voltage supply and its demand stays at or below 1.3A. It also accepts 85-264VAC input, which helps in applications that may see different AC input conditions.

Is the RS-15-12 suitable for outdoor use or only indoor enclosures?

The specs show an operating range of -20°C to +70°C, with output derating at higher ambient temperatures, and note 5G vibration resistance. No IP rating is listed, so the product data supports temperature capability but does not confirm weather-exposed outdoor use.

Does the job. Wish the terminals were a touch bigger.
