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 voltages. Pleas 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 GSM60B48-P1J to power 48V industrial networking or telecom equipment?

Yes, for equipment that is designed for 48V DC constant-voltage input. This model supplies up to 1.25A with a maximum output of 60W, so the load needs to remain within those limits.

Is this 48V power supply suitable for embedded communications devices or control interfaces?

It can be suitable for 48V embedded or communications hardware that requires a fixed-voltage DC source. The important electrical limits are 48V output, 1.25A maximum current, and 60W total power.

Will the GSM60B48-P1J work for 48V industrial monitoring or data collection systems?

It can be used where the end device expects 48V DC and the total draw stays at or below 1.25A. Because it is a constant-voltage supply, it should be paired only with loads specified for 48V input.

Can this model be used on a bench or in a control panel where AC input may vary?

Yes, the 80-264VAC input range supports use across a broad AC input range. On the DC side, it remains a 48V constant-voltage source with a 60W maximum output.

Is the GSM60B48-P1J suitable for outdoor environments or temperature extremes?

The specified operating range is -30°C to +70°C, with the output derated at higher temperatures according to the derating curve. No IP rating is listed, so outdoor or wet-location suitability cannot be verified from the provided specifications.
