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 GST18A28-P1J with a 28V industrial instrument or control accessory?
Yes, when the device is designed for constant 28V DC input and draws no more than 0.64A. This model is limited to 18W total output, so the application needs to stay inside that power range.
Is this supply suitable for 28V embedded hardware or OEM electronics?
It can be used for low-power 28V electronics that require a constant-voltage source rather than constant current. The supported AC input range is 85-264VAC, which helps when the same design is deployed in different regions.
Can the GST18A28-P1J power a small 28V automation or communications device?
It may be a fit for compact 28V equipment as long as the load does not exceed 0.64A. Buyers should confirm both the required voltage and the total power demand before selecting it.
What compatibility limits matter most for this 28V model?
The key checks are output voltage, current, and power: 28V DC, 0.64A maximum, and 18W maximum. A load outside those limits should use a different supply.
Can this model handle demanding temperature conditions?
Its specified operating temperature range is -30°C to +70°C, which supports use in a wide range of indoor industrial conditions. No IP rating is listed, so the published specs do not verify outdoor exposure resistance.
