Test conditions and notes8
  1. 1. All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
  2. 2. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
  3. 3. Tolerance: includes set up tolerance, line regulation, load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
  6. 6. Derating may be needed under low input voltage. Please check the derating curve for more details.
  7. 7. 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).
  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 GST120A24-R7B for a 24V industrial control panel or automation system?

Yes, if the load requires constant voltage 24V input, this model is aligned with that requirement. It provides up to 5A at 24V with a total output rating of 120W.

Is the GST120A24-R7B suitable for 24V monitoring, signaling, or embedded control equipment?

It can be a fit for 24V monitoring or embedded control devices that expect a regulated constant voltage supply. The available output is 24V and 5A, so the connected equipment needs to remain within a 120W budget.

Can this model be used for 24V industrial networking or edge devices?

It is appropriate for 24V industrial networking or edge hardware when the product input requirement is 24V constant voltage DC. The 85-264VAC input range also supports use in facilities with different AC mains standards.

What is the difference between the GST120A24-R7B and GST120A24-P1M?

The sibling specs shown for these two models are the same: 120W, 24V, and 5A. Based on the provided series data, there is no published difference in output rating.

Is the GST120A24-R7B suitable for outdoor use?

The product specs list an operating temperature range of -30°C to +70°C, which supports a broad temperature window. No IP rating is included here, so the provided data does not confirm protection for direct outdoor, wet, or dusty exposure.
