Test conditions and notes9

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. 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.
7. Derating may be needed under low input voltages. Pleas check the derating curve for more details.
8. 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).
9. 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 GSM40A05-P1J for a 5V embedded controller or SBC project?

It can work for 5V embedded hardware that needs constant voltage and draws up to 5A. With a 25W rating, it is better suited to moderate-power 5V systems rather than larger 5V loads.

Is this 5V power supply suitable for industrial HMI or logic electronics?

It can be suitable where the electronics are designed for 5V DC constant voltage input and the total demand stays within 25W. The 5A output gives more current headroom than low-current 5V adapters for control electronics.

Can the GSM40A05-P1J power 5V test, measurement, or lab devices?

Yes, for devices that specifically require 5V DC and do not exceed 5A. Its 80-264VAC input also makes it practical for benches or facilities with different AC supply standards.

Would this model fit a 5V automation accessory that runs continuously?

It can fit continuous-duty 5V accessories if their power draw stays within the unit's 25W limit. The operating temperature range of -30°C to +70°C supports use across a broad range of indoor equipment conditions.

Is the GSM40A05-P1J intended for outdoor use or exposed environments?

The stated specs provide a temperature range of -30°C to +70°C, but no IP rating is listed. Because enclosure protection is not specified, the product data does not confirm suitability for outdoor or wet locations.
