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 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. 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 720mm*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 “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
5. By using UVP circuit, PSU will not turn on direct by in AC continue ON/OFF condition within 5 sec.
6. 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).
7. This power supply does not meet the harmonic current requirements outlined by EN61000-3-2. Please do not use this power supply under the following conditions: a) the end-devices is used within the European Union, and b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal voltage, and c) the power supply is: - installed in end-devices with average or continuous input power greater than 75W, or - belong to part of a lighting system Exception: Power supplies used within the following end-devices do not need to fulfill EN61000-3-2 a) professional equipment with a total rated input power greater than 1000W; b) symmetrically controlled heating elements with a rated power less than or equal to 200W

FAQ

Can I use the SE-1000-12 for a large 12V industrial control panel or automation cabinet?

Yes, this is a constant-voltage 12V power supply rated for 83.3A and 999.6W. That output level fits high-demand 12V DC control panels, machine control cabinets, and other industrial systems that need a single high-capacity 12V source.

Is the SE-1000-12 suitable for powering multiple 12V embedded or communications devices from one supply?

It can be a fit when the combined load is 12V DC and stays within 83.3A and 999.6W. That makes it appropriate for centralized 12V distribution in embedded, industrial IT, or communications equipment where many devices share one high-power DC supply.

Can I use this 12V power supply for high-current 12V test benches or burn-in racks?

Yes, the 12V constant-voltage output and 83.3A current rating make it suitable for high-load 12V bench or rack use, as long as the total load stays within 999.6W.

Is the SE-1000-12 appropriate for indoor or outdoor environments?

The listed operating temperature is -20°C to +60°C, so that is the defined temperature range for use. No IP rating is provided in the listed specs, so the environmental sealing level is not specified and outdoor exposure suitability cannot be confirmed from the provided data alone.

How does the SE-1000-12 compare with other SE-1000 models?

Within the SE-1000 family, the 12V model is rated at 83.3A and 999.6W. Other listed versions are SE-1000-15 at 15V, 66.7A, 1000.5W; SE-1000-24 at 24V, 41.7A, 1000.8W; SE-1000-48 at 48V, 20.8A, 998.4W; SE-1000-9 at 9V, 100A, 900W; and SE-1000-5 at 5V, 150A, 750W.
