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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 5. 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 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).

FAQ
Can I use the PSPA-1000-48 for 48V industrial automation or motion control systems?
Yes, if the equipment requires a constant voltage 48V DC source. This model provides 1008W at 48V with up to 21A output, which suits higher-voltage industrial systems that do not run on 12V, 15V, or 24V rails.
Is the PSPA-1000-48 suitable for telecom or network equipment that uses 48V DC?
It can fit 48V DC telecom, communications, or network hardware when the load profile matches a constant voltage supply. The 1008W power rating and 21A output support larger 48V systems than lower-power alternatives.
Can this model power 48V embedded or industrial computing platforms?
Yes, for platforms built around a 48V DC input architecture. Its 48V output and 21A capacity make it appropriate where a higher-voltage DC bus is preferred for industrial or distributed system design.
Would the PSPA-1000-48 work for a centralized 48V DC distribution shelf?
It is suitable for centralized 48V distribution inside equipment when the total load stays within 1008W and 21A. The wide 90-264VAC input range also supports installations across different AC mains conditions.
Is the PSPA-1000-48 rated for outdoor use?
The provided specs list an operating temperature range of -20°C to +70°C, but they do not list an IP rating. Based on that information, it is better classified for protected indoor or enclosure-based use rather than direct outdoor exposure.
How does the PSPA-1000-48 compare with the other PSPA-1000 models?
The PSPA-1000-48 is rated for 1008W, 48V, and 21A. The other listed series options are PSPA-1000-12 at 960W, 12V, 80A; PSPA-1000-15 at 960W, 15V, 64A; and PSPA-1000-24 at 1008W, 24V, 42A.
