Overview

GSM36E18-P1J is the 18V output model of this series: rated current 2A, typical efficiency 87%. Type P1J: Plug for standard model, 2.1φ x 5.5φ x11mm, c+, tuning fork type.

GSM36E is a highly reliable, 36W wall-mounted style single-output green medical adaptor series. This product is equipped with a 2-pin (no FG) standard European 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 miniature 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, GSM36E is compliant with EU ErP and meet Code of Conduct(CoC) Version 5; 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. GSM36E is approved with the international medical safety certificates.

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 GSM36E18-P1J to power 18V industrial controllers or small automation devices?

Yes, it is a constant-voltage 18V power supply rated for 36W and 2A output. That makes it suitable for 18V equipment whose load stays within 2A and 36W.

Is this 18V adapter suitable for embedded systems or bench equipment that runs on 18V DC?

It can be a fit for embedded or electronic equipment designed for a constant 18V DC source. The available output is 2A with a total power limit of 36W, so the device's 18V demand needs to stay within those ratings.

Can the GSM36E18-P1J be used for low-power industrial sensors or control accessories that need 18V?

It is intended for constant-voltage 18V applications and can support loads up to 2A. For control accessories, sensor groups, or similar 18V DC devices, the key check is whether the combined demand remains within 36W.

Is the GSM36E18-P1J appropriate for indoor or outdoor environments?

The listed operating temperature range is -25°C to +60°C, which defines the temperature window from the provided specs. The provided data does not include an IP rating, so outdoor or water-exposed suitability is not established by the listed specifications alone.

How do I know if this 18V power supply is correctly sized for my load?

Match the load to a constant 18V source and keep the requirement at or below 2A and 36W. If the equipment needs more than 2A or more than 36W, this model is undersized.
