Test conditions and notes8

1.All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
2.DC voltage: The output voltage set at point measure by plug terminal & 50% load.
3.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
4.Tolerance: includes set up tolerance, line regulation, load regulation.
5.Line regulation is measured from low line to high line at rated load.
6.Load regulation is measured from 10% to 100% rated load.
7.Derating may be needed under low input voltage. Please check the derating curve for more details.
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 GST25A12-P1J for 12V PLC accessories or industrial control hardware?

Yes, if the accessory or control hardware is designed for 12V DC input and stays within 2.08A and 25W. This constant-voltage supply is appropriate for low-power industrial electronics that require a steady 12V source. The wide 85-264VAC input is also useful where AC input conditions vary.

Is this 12V model suitable for small CCTV, sensor, or automation devices?

It can be suitable for 12V CCTV, sensing, or automation devices that do not exceed 2.08A or 25W. The output is fixed at 12V, so the connected load should be designed for 12V constant-voltage operation. This keeps it in the range of lower-power 12V equipment rather than higher-draw systems.

Can the GST25A12-P1J power a 12V embedded computer or communications device?

Yes, if the device requires 12V DC and its total load is within 25W and 2.08A. That makes it relevant for compact embedded, communications, or interface hardware built around a 12V input. The housing is 93.0 x 54.0 x 36.0 mm, which helps in tighter installations.

Is this power supply intended for outdoor conditions?

The operating temperature range is -30C to +70C, but no IP rating is listed in the provided specs. Without a stated IP rating, it is better treated as a unit for indoor or protected use rather than open outdoor exposure. Environmental protection would need to come from the enclosure around it.

How do I size this 12V adapter for my load?

Use it only with equipment that requires 12V DC and stays at or below 2.08A and 25W. If the load needs more current or a different voltage, this model is not the correct match. The key compatibility check is exact 12V requirement plus total load within the rated output.
