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-480-24 for 24V automation and control equipment?
Yes, it provides a single 24V output rated for 480W and 20A. That matches industrial and automation systems designed around a 24V DC power rail.
Is the SP-480-24 suitable for 24V sensors, controllers, and industrial peripherals with higher total load?
It can support 24V DC loads up to 480W total and up to 20A output current. This makes it relevant for larger 24V systems with multiple devices on the same supply.
Can this power supply be used for 24V LED, display, or signage systems?
Yes, if the system is designed for 24V DC and stays within 480W and 20A, this model is a fit. It is a single-output 24V supply intended for higher-power DC applications.
Is the SP-480-24 meant for indoor or outdoor operating conditions?
The listed operating temperature range is -20°C to +60°C. The provided specs do not include an IP rating, so they do not document outdoor exposure protection.
How does the SP-480-24 differ from the other SP-480 family models?
The SP-480-24 is rated at 480W with a 24V output and 20A current. Other listed SP-480 models are SP-480-12 at 480W, 12V, 40A; SP-480-15 at 480W, 15V, 32A; 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.
