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-P1M for a 24V PLC, controller, or automation device?

Yes, this unit is a constant voltage 24V model with up to 5A output current. That makes it a reasonable fit for 24V industrial control or automation equipment that stays within a 120W load requirement.

Is this a good power supply for 24V sensors, gateways, or embedded hardware?

It can be used with 24V embedded or automation hardware that is specified for constant voltage DC input. The available output is 24V at up to 5A, with a total power rating of 120W.

Can the GST120A24-P1M power 24V lab or industrial communication equipment?

It is suitable for 24V communication, monitoring, or lab equipment when the device expects a regulated 24V constant voltage source. The 85-264VAC input range is also useful where AC supply conditions vary across sites.

How does the GST120A24-P1M compare with the GST120A24-R7B?

Both models are rated 120W, 24V and 5A, so their output ratings match. They differ in the DC plug (P1M: 5.5/2.5mm barrel; R7B: 4-pin mini-DIN) and typical efficiency (89.5% for P1M, 90.5% for R7B).

Can I use the GST120A24-P1M in cold rooms, warm plant areas, or other temperature-variable indoor spaces?

The specified operating temperature range is -30°C to +70°C, so the unit is rated for a wide indoor temperature span. The data provided does not include an IP rating, so temperature range alone should not be treated as proof of outdoor or washdown suitability.
