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 GST36B48-P1J for a 48V industrial control load?

Yes, if the equipment requires constant 48V and draws no more than 0.75A. This unit is rated for 36W total output, so it is suited to lower-power 48V control and automation loads within that limit.

Is this power supply appropriate for 48V telecom or network equipment?

It can be appropriate for 48V devices that accept a constant-voltage input and stay within 36W. The maximum output current is 0.75A, so the connected load needs to remain at or below that value.

Can the GST36B48-P1J power a 48V embedded system or OEM module?

Yes, for 48V embedded or OEM equipment that needs a regulated constant-voltage source. The output is 48V at up to 0.75A, with a total power rating of 36W.

Is the GST36B48-P1J a fit for low-power 48V automation devices?

It is designed for constant 48V output and can support low-power automation devices that stay within 0.75A. That makes it more suitable for lighter 48V loads rather than higher-current equipment.

Can this 48V adapter be used in indoor-only or outdoor installations?

The stated operating temperature range is -30°C to +70°C, so temperature tolerance is broad. However, no IP rating is provided in the specs, so outdoor exposure is not defined by the listed data.
