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-1000-24 for a 24V PLC or automation control cabinet?

Yes, this model is well suited to 24V industrial automation systems that need a constant voltage source. It provides 1008W at 24V with up to 42A output, which fits larger PLC, I/O, and control cabinet loads.

Is the PSPA-1000-24 appropriate for industrial sensors, relays, and 24V control devices on one supply?

It can support a centralized 24V DC bus for multiple industrial devices as long as the total load stays within 1008W and 42A. The constant voltage output is aligned with common 24V control architectures used in automation equipment.

Can this 24V power supply be used for embedded systems or industrial computers that run on 24V DC?

Yes, if the system is designed for a 24V constant voltage input. The 24V output and 42A capacity make it a better fit for higher-power 24V embedded platforms than the 12V, 15V, or 48V variants.

Is the PSPA-1000-24 suitable for machine control systems that need more than a typical small DIN rail supply?

It is intended for higher-power 24V applications where a single supply may need to support substantial cabinet demand. With 1008W available, it sits above lower-power 24V supplies and is aimed at heavier control-system loads.

Can the PSPA-1000-24 operate in warm factory enclosures?

The specified operating range is -20°C to +70°C, so the temperature rating supports use in demanding indoor industrial environments. Since no IP rating is listed in the provided specs, it should be treated as a protected-enclosure product rather than an exposed outdoor unit.

What are the differences between the PSPA-1000-24 and the other PSPA-1000 versions?

The PSPA-1000-24 is rated at 1008W, 24V, and 42A. The sibling models listed are PSPA-1000-12 at 960W, 12V, 80A; PSPA-1000-15 at 960W, 15V, 64A; and PSPA-1000-48 at 1008W, 48V, 21A.
