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.
