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 GST25A28-P1J for equipment that requires 28V DC power?
Yes, if the equipment is designed for 28V DC input and uses constant voltage power. This model provides 28V output with up to 0.89A and 25W total.
Is the GST25A28-P1J a fit for 28V industrial or embedded control devices?
It can be used with 28V control, embedded, or instrumentation loads that stay within its 25W and 0.89A rating. The output type is constant voltage, so it is intended for devices that expect a fixed 28V supply.
Can this power supply support a small 28V automation accessory or module?
Yes, for small 28V automation hardware where the load current does not exceed 0.89A. The key match points are the 28V output and the 25W maximum power rating.
Is the GST25A28-P1J suitable for worldwide AC input ranges?
The input range is 85-264VAC, which covers a wide AC input span. That makes it suitable for equipment designs that need one supply specification across different mains environments within that input range.
Can the GST25A28-P1J be used in outdoor or harsh temperature conditions?
The specified operating temperature range is -30°C to +70°C. No IP rating is provided in the specs, so the data does not establish outdoor, washdown, or weather-exposed suitability.
