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 0.1uf & 47uf parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. TSW1: Detect on heatsink of power transistor. TSW2: Detect on heatsink of output diode.
- 5. 33% Duty cycle maximum within every 30 minute. Average output power should not exceed the rated power.
- 6. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 7. 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)
- 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 SP-480-12 for a 12V industrial control panel or automation cabinet?
Yes, it is a 12V single-output power supply rated for 480W and 40A. Its 85-264VAC input range also fits facilities that need broad AC input compatibility.
Is the SP-480-12 suitable for high-current 12V LED lighting or signage systems?
It can support 12V lighting or signage systems that need up to 480W total and up to 40A output current. This model is intended for applications that require a single 12V output at higher power.
Can this 12V power supply run embedded or DC-powered industrial electronics that need a large 12V rail?
Yes, the SP-480-12 is designed for 12V systems and provides up to 40A from a single output. That makes it relevant for embedded, industrial, or automation equipment built around a 12V DC power bus.
Is the SP-480-12 appropriate for indoor or outdoor use?
The published specs list an operating temperature range of -20°C to +60°C. No IP rating is listed in the provided specs, so the product data supports temperature guidance but does not establish outdoor or weather-exposed suitability.
How does the SP-480-12 compare with the other SP-480 models?
Within the SP-480 family, the SP-480-12 is 480W at 12V and 40A. Other listed SP-480 versions are SP-480-15 at 480W, 15V, 32A; SP-480-24 at 480W, 24V, 20A; SP-480-3.3 at 280.5W, 3.3V, 85A; SP-480-48 at 480W, 48V, 10A; and SP-480-5 at 425W, 5V, 85A.
