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. 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 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 GSM36B48-P1J for 48V industrial communication or control equipment?

Yes, if the equipment is designed for constant voltage 48V DC input. This power supply delivers up to 0.75A, with a total output rating of 36W.

Is this 48V model suitable for embedded or network-related devices that operate on 48V DC?

It can be used for 48V DC devices that need a regulated constant voltage source. The load must stay within 0.75A and the overall 36W limit.

Can this power supply run a 48V industrial instrument or interface module?

It is suitable for 48V instrumentation or interface hardware when the device demand does not exceed 0.75A. The 80-264VAC input range also supports use across a wide range of AC supply conditions.

How do I confirm this 48V supply will work with my device?

The device should require constant voltage 48V DC and draw no more than 0.75A, with total power at or below 36W. If the device needs another voltage, this supply is not a compatible replacement.

Is the GSM36B48-P1J rated for outdoor use?

The provided specifications state an operating temperature range of -25°C to +60°C. No IP rating is included, so the supplied data does not confirm protection for outdoor, wet, or dust-prone environments.
