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 GST25B24-P1J for 24V PLC accessories or control circuits?

Yes, it can fit 24V PLC accessories or control circuits that need constant 24V DC and draw no more than 1.04A. Its 25W rating makes it suitable for lighter-duty 24V electronics rather than larger automation loads.

Is this a suitable power supply for 24V sensors, transmitters, or interface modules?

It can support 24V sensors, transmitters, or interface modules if the total load stays within 1.04A. Because it provides constant voltage, it is intended for equipment that specifies 24V DC input.

Would the GST25B24-P1J work for compact 24V industrial networking or communications devices?

It can work for compact 24V communications or networking equipment when the device requires 24V DC and remains within the 25W output limit. The 85-264VAC input range also supports use across varied AC input conditions.

Can I use this model for 24V embedded or machine-level electronics?

It can be used for 24V embedded or machine-level electronics that need a fixed 24V supply and do not exceed 1.04A. Its 79 x 54 x 33 mm dimensions help in space-constrained equipment layouts.

Is the GST25B24-P1J appropriate for indoor and outdoor environments?

The listed operating temperature range is -30C to +70C, which covers a wide span of temperatures. No IP rating is provided in the supplied specs, so the available data supports temperature review but does not confirm outdoor exposure resistance.
