Overview

GSM18U24-P1J is the 24V output model of this series: rated current 0.75A, typical efficiency 87%.

GSM18U is a highly reliable, 18W wall-mounted style single-output green medical adaptor series. This product is equipped with a 2-pin (no FG) standard USA AC power plug, adopting the input range from 80VAC to 264VAC. The entire series supplies different output voltages between 5VDC and 48VDC that can satisfy the demands for various kinds of miniaturize medical devices. The circuitry design meets the international medical standards (2 × MOPP), having an ultra low leakage current (<50 μA), fitting the medical devices in direct electrical contact with the patients. With the efficiency up to 88% and the extreme low no-load power consumption below 0.1W, GSM18U is compliant with USA EISA 2007/DoE and Canada NRCan; the supreme feature allows the adaptor to save the energy when it is either under the operating mode or the standby mode. The entire series utilizes the 94V-0 flame retardant plastic case, providing the double insulation that effectively prevents electrical shock. GSM18U is approved with the international medical safety certificates.

Test conditions and notes8
  1. 1. All parameters are specified at 115VAC input, rated load, 25℃ 70% RH ambient.
  2. 2. DC voltage: The output voltage set at point measure by plug terminal & 50% load.
  3. 3. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
  4. 4. Tolerance: includes set up tolerance, line regulation, load regulation.
  5. 5. Line regulation is measured from low line to high line at rated load.
  6. 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. 7. Derating may be needed under low input voltage. Please check the derating curve for more details.
  8. 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 GSM18U24-P1J for a 24V sensor hub or compact automation device?

Yes, if the equipment is designed for constant voltage 24V DC and stays within 0.75A and 18W. That makes it suitable for low-power automation, monitoring, and control devices that use a 24V input.

Is this 24V adapter suitable for small industrial communication or control electronics?

It can be a fit for compact industrial electronics that require regulated 24V constant voltage. The output capability is 24V at up to 0.75A, with 18W total power available.

Can the GSM18U24-P1J power a low-power embedded or IT device that needs 24V DC?

Yes, for embedded or IT hardware specifically rated for 24V DC constant voltage operation. The load should remain at or below 0.75A and 18W.

Is the GSM18U24-P1J suitable for outdoor installation or dusty areas?

The listed operating temperature range is -25°C to +60°C, so the temperature specification is clearly defined. No IP rating is provided in the product specs, so these details alone do not confirm outdoor or contamination-resistant use.
