Overview

GSM18U09-P1J is the 9V output model of this series: rated current 2A, typical efficiency 84%.

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 GSM18U09-P1J for a 9V industrial sensor or small control module?

Yes, this model provides constant voltage output at 9V with up to 2A and 18W available. It is a fit for industrial or embedded equipment that specifically requires regulated 9V DC and stays within that current and power limit.

Is this 9V power supply suitable for embedded electronics or evaluation hardware?

It can be suitable for embedded boards, test fixtures, and low-power control electronics that call for 9V constant voltage. The key match points are the 9V output, 2A maximum output current, and 18W power rating.

Can the GSM18U09-P1J power a small automation interface or data-collection device?

It is intended for constant-voltage 9V loads, so it can work with compact automation or monitoring devices rated for 9V DC. The connected load needs to remain within 18W and 2A.

Is the GSM18U09-P1J appropriate for outdoor or harsh-environment use?

The published operating temperature range is -25°C to +60°C, which defines its temperature envelope. No IP rating is listed in the provided specs, so these specifications do not by themselves confirm outdoor, wet-location, or washdown suitability.
