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 GST18B09-P1J for a 9V industrial sensor interface or control module?
Yes, if the module is designed for 9V DC input and the total load stays within 2A and 18W. This unit provides constant-voltage 9V output, which suits electronics that expect a fixed 9V supply. The 85-264VAC input also supports deployment where AC source range may vary.
Is this 9V power supply suitable for a compact communications or monitoring device?
It can be suitable for a communications or monitoring device that specifies 9V constant voltage and requires no more than 2A or 18W. That output level fits moderate-power electronics better than equipment needing higher current headroom. Buyers should match both voltage and total power requirement to this model.
Can the GST18B09-P1J power 9V lab, bench, or diagnostic equipment?
Yes, it is a practical choice for 9V bench or diagnostic electronics that operate within 2A and 18W. Because it is a constant-voltage supply, it fits equipment that expects a regulated 9V rail rather than a variable source. Its 191.5 g weight also makes it easy to use with portable or compact setups.
Would this model work for a 9V embedded controller used in automation or IT systems?
It can, provided the controller calls for 9V DC and its total draw does not exceed 2A or 18W. The wide 85-264VAC input range is useful for equipment deployed in mixed-site power environments. At 79.0 × 54.0 × 33.0 mm, it also fits smaller equipment footprints.
Can the GST18B09-P1J be used outdoors or in unprotected locations?
The specified operating temperature range is -30°C to +70°C, with load derating required at the upper end of that range (see the derating curve), so the temperature window is broad. However, no IP rating is provided in the listed specs, so it should not be treated as weatherproof or waterproof. It is better suited to indoor use or placement inside a protective enclosure.
