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 GST25A48-P1J for a 48V networking or communications device?

It can be used with 48V equipment that accepts constant voltage input and requires no more than 0.52A. The unit is rated for 48V output and 25W maximum power.

Is the GST25A48-P1J suitable for 48V industrial control electronics?

Yes, for 48V industrial or embedded electronics that stay within the 25W and 0.52A output limits. It is a constant voltage supply, so the connected load should be designed for 48V DC input.

Can this model power a small 48V automation or monitoring unit?

It is a reasonable fit for compact 48V automation, monitoring, or interface equipment that draws no more than 0.52A. Its fixed output is 48V DC, with a total power rating of 25W.

How do I know if 25W is enough for my 48V device?

Match the device requirement against the supply's 48V, 0.52A, and 25W limits. If the load needs more than 0.52A at 48V or more than 25W total, this model is undersized.

Is the GST25A48-P1J rated for outdoor use or temperature extremes?

The operating temperature range is -30°C to +70°C, so the temperature specification is broad. However, no IP rating is listed, so the provided specs do not confirm outdoor or moisture-exposed use.
