Overview

GSM36U12-P1J is the 12V output model of this series: rated current 3A, typical efficiency 86%.

GSM36U 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 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 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, GSM36U is compliant with USA EISA 2007/DoE and Canada NRCan; the superme 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. GSM36U is approved with the international medical safety certificates.

Test conditions and notes8

1. All parameters are specified at 115VAC 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 GSM36U12-P1J for a 12V industrial HMI or control accessory?

Yes, if the device requires constant 12V DC and draws no more than 3A. This model is rated for 36W total, which makes it suitable for smaller 12V industrial control and HMI-related loads within that range.

Is this a good choice for 12V embedded systems or edge devices?

It can be, as long as the equipment is designed for constant 12V input and stays at or below 3A. The 80-264VAC input range is also useful when the adapter may be used across different AC mains environments.

Can this 12V power supply run small IT or networking hardware that uses 12V DC?

Yes, for 12V DC hardware that needs constant voltage and does not exceed 36W or 3A. Buyers should verify the device's required DC voltage and current against the 12V, 3A output of this model.

Can I use the GSM36U12-P1J outdoors or in cold environments?

Its stated operating temperature is -25C to +60C, with output derating per the derating curve at the upper end of that range. However, no IP rating is listed in the provided specs, so outdoor exposure to water or dust is not confirmed.
