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. 33% Duty cycle maximum within every 15 seconds. Average output power should not exceed the rated power.
- 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 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 SCP-35-12 for a small 13.8V industrial control panel?
Yes, this model is a constant-voltage 13.8V supply rated for 2.6A and 35.9W. That makes it suitable for small 13.8V control electronics, panel devices, or embedded hardware that stay within that DC load.
Is the SCP-35-12 a fit for low-power telecom or monitoring equipment that runs on 13.8V DC?
It can be, if the equipment requires a regulated 13.8V DC source and does not exceed 2.6A or 35.9W. The wide 85-264VAC input also helps in facilities that may see different AC mains standards.
Can this power supply support embedded or automation electronics with battery-related voltage requirements?
It supports embedded or automation electronics with battery-related voltage requirements by providing constant-voltage output at 13.8V and an output voltage detection signal. It features a connector for an external NTC thermistor to enable temperature compensation, though the sensor itself is not included with the power supply.
Is the SCP-35-12 suitable for outdoor or harsh-location use?
The operating temperature range is -20°C to +60°C, so the thermal range suits many indoor equipment spaces and protected enclosures. No IP rating is listed in the provided specs, so outdoor or washdown suitability is not established from this data alone.
How does the SCP-35-12 compare with the other SCP series models?
Within this group, the SCP-35-12 is 35.9W at 13.8V and 2.6A. The siblings are SCP-35-24 at 38.6W, 27.6V, 1.4A; SCP-50-12 at 49.7W, 13.8V, 3.6A; SCP-50-24 at 49.7W, 27.6V, 1.8A; SCP-75-12 at 74.5W, 13.8V, 5.4A; and SCP-75-24 at 74.5W, 27.6V, 2.7A.
