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 GST25B05-P1J for 5V embedded systems or single-board computers?
Yes, if the equipment requires a 5V constant voltage supply and the load stays within 4A and 20W. That makes it suitable for many embedded and low-voltage electronic applications designed around 5V input.
Is the GST25B05-P1J suitable for 5V USB-class electronics or peripherals?
It can support 5V electronic devices or peripherals that need a regulated 5V source and draw no more than 4A. The total available output power is 20W.
Can this 5V power supply run small automation controllers or logic devices?
Yes, for 5V control logic, embedded boards, or automation accessories that fall within the 4A output current limit. It is a constant voltage supply, so it should be paired only with loads intended for 5V DC.
Is the GST25B05-P1J a good match for high-current 5V loads?
This model provides up to 4A at 5V, which is relatively high current within this product group. The load still needs to remain at or below 20W total and use constant 5V input.
Can the GST25B05-P1J be used outdoors or in cold areas?
Its operating temperature range is -30°C to +70°C. No IP rating is shown in the provided specs, so outdoor or wet-environment use is not established here.
