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 voltage. Please 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 GST280A20-C6P for a 20V industrial or automation load?

Yes, if the load requires constant 20V DC and does not exceed 13A. This model is rated for 260W, making it suitable for higher-power 20V industrial electronics.

Is the GST280A20-C6P suitable for a 20V embedded system or control assembly?

It can be used with embedded or control assemblies designed for a regulated 20V DC input. The supply provides up to 260W, which gives more capacity for larger 20V systems than lower-wattage adapters.

Can this 20V power supply support a test, inspection, or bench application?

Yes, for bench or production equipment that specifies constant 20V DC. The available output is 13A, so it fits heavier 20V loads as long as the total power stays within 260W.

Is GST280A20-C6P appropriate for 20V industrial peripherals or auxiliary equipment?

It is appropriate for 20V peripherals and auxiliary equipment that need a stable constant-voltage source. The wide 85-264VAC input range can also help when the same equipment is used across different AC mains environments.

Can I use the GST280A20-C6P outside or in demanding temperature conditions?

The operating temperature range is -30°C to +70°C, with load derating at higher ambient temperatures per the derating curve. An IP rating is not included in the specs, so outdoor exposure suitability is not confirmed by the provided product data.
