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 GSM40B24-P1J for a 24V PLC or industrial automation device?

Yes, this model provides constant voltage 24V output and is rated for 40W with 1.67A maximum current. It is suitable for PLCs or automation devices that require 24V DC and stay within that 1.67A limit.

Is the GSM40B24-P1J suitable for 24V sensors, relays, or control interfaces?

It can power 24V DC control hardware when the total load remains within 40W and 1.67A. Since it is a constant voltage unit, it should be matched to equipment designed for a 24V constant voltage supply.

Can this 24V power supply be used for embedded or communications equipment that needs 24V DC?

It can be used where the equipment input requirement is 24V DC and the current draw does not exceed 1.67A. The 80-264VAC input range is also useful for equipment deployed in different mains environments.

Would the GSM40B24-P1J work for low-power 24V industrial accessories in a cabinet?

Yes, it is a fit for low-power 24V accessories if the total demand stays within 40W. Its dimensions are 125.0 × 50.0 × 31.5 mm, which may help when planning cabinet space.

Is the GSM40B24-P1J appropriate for outdoor installations?

The operating temperature range is -30°C to +70°C, so the temperature spec is broad. However, no IP rating is listed in the provided specs, so outdoor or washdown suitability is not established here.
