Overview

GSM18E12-P1J is the 12V output model of this series: rated current 1.5A, typical efficiency 85%. Type P1J: Plug for standard model, 2.1$\phi$ x 5.5$\phi$ x11mm, c+, tuning fork type.

GSM18E 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 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 miniaiture 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, GSM18E 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. GSM18E 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 GSM18E12-P1J for a 12V sensor, relay, or control device?

Yes, if the equipment requires constant 12V DC and the total load does not exceed 1.5A. With 18W output, this model fits many small 12V control, sensing, and relay-driven applications.

Is this 12V power supply suitable for a compact CCTV or access-control component?

It can be suitable for 12V security, access, or monitoring components when the device is rated for 12V DC input and draws no more than 1.5A. The constant voltage output is appropriate for electronics that expect a fixed 12V supply.

Would the GSM18E12-P1J work for a 12V automation panel accessory?

Yes, it may be used for small panel accessories, interface modules, or low-power automation components that need regulated 12V DC. The load still needs to remain within the 18W and 1.5A ratings.

Can this model power a 12V modem, router accessory, or embedded terminal?

It may be a fit for 12V communications or embedded equipment if the input requirement is 12V DC and the current draw stays at or below 1.5A. Its 80-264VAC input range also supports use in varied AC supply environments.

Is the GSM18E12-P1J suitable for outdoor use?

The operating temperature range is listed as -25°C to +60°C, which defines the allowed temperature window. The provided specs do not include an IP rating, so direct outdoor exposure should not be assumed without an enclosure that provides the necessary environmental protection.
