Test conditions and notes6

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. 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).
6. 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-1500-12 for large 12V industrial control or automation loads?

Yes, this is a constant-voltage 12V power supply with up to 125A output current. It can fit larger 12V automation or control loads when the combined demand stays within 1500W.

Is the SE-1500-12 suitable for centralized 12V DC power distribution in a machine or panel?

It can support centralized 12V DC loads because it provides a single constant-voltage 12V output. The available capacity is 125A and 1500W, so the combined load has to stay within those limits.

Can this power 12V embedded systems or high-current 12V electronics in one enclosure?

Yes, for 12V DC electronics that need a constant-voltage source, this model provides substantial current headroom. The total connected load must stay within 125A and 1500W.

How does the SE-1500-12 compare with the other SE-1500 versions?

The listed SE-1500 models are SE-1500-5 at 5V, 300A, 1500W; SE-1500-12 at 12V, 125A, 1500W; SE-1500-15 at 15V, 100A, 1500W; SE-1500-24 at 24V, 62.5A, 1500W; SE-1500-27 at 27V, 55.6A, 1501.2W; and SE-1500-48 at 48V, 31.3A, 1502.4W. Compared with the other versions, this model keeps the same series power class while changing voltage and maximum current.

Can the SE-1500-12 be used outdoors or in hotter operating conditions?

The provided specs list an operating temperature range of -20°C to +70°C, with output derated at higher temperatures according to the derating curve. No IP rating is provided, so outdoor exposure cannot be confirmed from these specs alone.
