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 GSM25B24-P1J to power a 24V PLC accessory or small automation module?

Yes, this model is designed for constant-voltage 24V output and can supply up to 25W or 1.04A. That makes it appropriate for compact 24V automation modules, PLC accessories, or control devices that stay within those limits.

Is this 24V power supply a good fit for industrial sensors or control electronics?

It can be a good fit for 24V control electronics, sensors, or monitoring devices that need a fixed 24V DC source and do not exceed 1.04A. The 80-264VAC input range also supports use in locations with different AC mains standards.

Can this unit power a compact 24V embedded or communications device?

Yes, if the device is designed for 24V constant-voltage input and its load is within 25W. For higher-power communications or automation hardware, the 1.04A output ceiling may be the limiting factor.

What kind of 24V load size is this model intended for?

This supply is intended for lower-power 24V loads up to 25W total. In current terms, that means the connected equipment should stay at or below 1.04A.

Can I use the GSM25B24-P1J in unheated or warmer equipment areas?

The specified operating range is -25°C to +60°C, with output derating at the warmer end per the sheet's derating curve, so it covers cold indoor spaces and moderately warm equipment environments. The specs provided do not include an IP rating, so exposure to rain, spray, or dust-heavy outdoor conditions is not confirmed here.
