Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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 360mm*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 http://www.meanwell.com)
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.

FAQ

Can I use the SP-320-12 for a 12V industrial automation panel?

Yes, if the panel and its connected 12V devices stay within 300W and 25A. Its constant voltage 12V output fits industrial control loads that require a regulated 12V DC supply.

Is the SP-320-12 a good fit for 12V security, access control, or monitoring equipment?

It can be used for 12V systems where the total load does not exceed 300W or 25A. That makes it relevant for larger 12V security and control setups that need more capacity than lower-wattage 12V supplies.

Can this model power a 12V embedded computer or communications system?

Yes, for equipment designed for 12V DC input and a combined demand within 300W and 25A. The wide 88-264VAC input also supports deployment across different AC input environments.

Would the SP-320-12 work for 12V LED signage or other 12V DC loads with substantial current demand?

It can support 12V loads up to 300W with 25A available output current. For signage, display, or other 12V systems, the deciding factor is whether the full connected load stays inside those limits.

Can the SP-320-12 be used outdoors or in unprotected areas?

The specified operating temperature range is -20°C to +65°C, but no IP rating is provided in the product data. That means temperature limits are defined, while outdoor exposure or wet-location suitability is not established by these specs.

How does the SP-320-12 compare with other SP-320 models?

The listed SP-320 variants include SP-320-12 at 300W, 12V, 25A; SP-320-27 at 315.9W, 27V, 11.7A; SP-320-36 at 316.8W, 36V, 8.8A; and SP-320-48 at 321.6W, 48V, 6.7A. They share the same series size class, but differ in output voltage and available current.
