Test conditions and notes8
  1. 1.All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
  2. 2.DC voltage: The output voltage set at point measure by plug terminal & 50% load.
  3. 3.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
  4. 4.Tolerance: includes set up tolerance, line regulation, load regulation.
  5. 5.Line regulation is measured from low line to high line at rated load.
  6. 6.Load regulation is measured from 10% to 100% rated load.
  7. 7.Derating may be needed under low input voltage. Please check the derating curve for more details.
  8. 8.The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the 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 )

FAQ

Can I use the GST25B09-P1J for 9V industrial sensors or monitoring devices?

It can be used for 9V industrial or monitoring equipment that requires a constant 9V DC supply and draws no more than 2.55A. With a 23W output rating, it fits lower-power 9V loads rather than equipment with higher startup or running demand.

Is this power supply suitable for a 9V embedded system or controller?

Yes, if the embedded system is designed for constant 9V DC input and stays within 2.55A. The constant-voltage output makes it a better match for fixed-voltage electronics than for loads that require current regulation.

Can the GST25B09-P1J power 9V IT or communications accessories?

It can support 9V IT or communications accessories when their input requirement is 9V DC and their load remains within 23W. The 85-264VAC input range also makes it usable across a wide range of AC supply conditions.

Would this work for 9V automation devices inside a control enclosure?

It can fit 9V automation accessories inside an enclosure if they need constant 9V output and do not exceed 2.55A. Its compact 79 x 54 x 33 mm size also helps where space is limited.

Is the GST25B09-P1J suitable for outdoor or harsh-environment use?

The listed operating temperature is -30C to +70C, so the temperature range is broad. However, no IP rating is provided in the supplied specs, so outdoor exposure or washdown suitability cannot be confirmed from this data alone.
