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 GST25B48-P1J for a 48V telecom or network device?

Yes, if the equipment requires constant 48V DC and draws no more than 0.52A. This model is rated for 25W, so it is intended for lower-power 48V telecom, communications, or network hardware.

Is this power supply suitable for 48V industrial communication equipment?

It can support industrial communication or control equipment designed for a steady 48V DC supply. The output is limited to 25W at 0.52A, so it should be matched to lighter-duty 48V loads.

Can the GST25B48-P1J power a small 48V embedded system?

Yes, for embedded systems that are specified for constant 48V input and remain within 0.52A current draw. Its 85-264VAC input range also makes it usable across a broad range of AC mains conditions.

Is GST25B48-P1J appropriate for a 48V automation accessory or sensor platform?

It is a fit for 48V automation accessories or related electronics that need constant voltage rather than a current-regulated output. The available capacity is 25W, so the total 48V load must stay under 0.52A.

Can this 48V adapter be used in cold or hot operating areas?

The specified operating temperature range is -30°C to +70°C, which covers a wide span for indoor equipment use. No IP rating is provided in the specs, so outdoor exposure suitability cannot be confirmed from the listed data.
