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 GST280A48-C6P for 48V telecom or network equipment?

Yes, it can suit 48V telecom or network hardware that requires a constant-voltage 48V DC source. This model is rated for 280.32W and 5.84A, so the connected 48V load must remain within those limits.

Is this power supply appropriate for 48V industrial automation devices?

It is appropriate for 48V industrial electronics that are designed for constant-voltage input. The unit provides 48V output at up to 5.84A, which fits moderate-power 48V control and automation loads.

Can the GST280A48-C6P power 48V LED or display systems?

Yes, it can be used with 48V LED or display systems that require constant-voltage operation. The available output is 280.32W total, so the full 48V load needs to stay within 5.84A.

Would this model work for 48V embedded or industrial computing hardware?

It can be used for embedded or industrial computing hardware that is specified for 48V DC input. Its 85-264VAC input range also makes it practical where the incoming AC supply may vary.

Can I use the GST280A48-C6P in cold or hot environments?

The specified operating temperature range is -30°C to +70°C, with load derating at higher ambient temperatures per the derating curve. The specs provided do not include an IP rating, so suitability for outdoor or washdown-style exposure is not established here.
