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

What are the main output specifications of the Mean Well GSM36B12-P1J?

The GSM36B12-P1J is a 36W AC-DC medical adaptor with a regulated 12V DC output and a rated current of 3A. This model uses the P1J DC plug format, specified as 2.1 mm x 5.5 mm x 11 mm with center positive polarity.

Is the GSM36B12-P1J suitable for medical applications?

Yes. This model is medical safety approved and is specified with 2 x MOPP isolation between primary and secondary. It also lists ANSI/AAMI ES60601-1, ES60601-1-11, and TUV EN60601/60601-1-11 approvals, along with leakage current below 50uA.

What input voltage range does the GSM36B12-P1J support?

The GSM36B12-P1J supports a universal input range of 80 to 264VAC, and it also accepts 113 to 370VDC. That full-range input makes it suitable for use across many regions and power environments without needing a region-specific version.

Can this power supply be used in demanding operating environments?

It is rated for operation from -25°C to +60°C, subject to the manufacturer's derating guidance. The unit also has built-in overload protection (hiccup mode, auto-recovery) and over voltage protection.

What makes the GSM36B12-P1J different from a standard consumer power adaptor?

This model is positioned as a higher-spec adaptor because it combines medical approvals, 2 x MOPP isolation and very low touch current below 50uA. It also offers 86% typical efficiency and Class B conducted and radiated emissions.

What physical format and cable details does this model have?

The GSM36B12-P1J is a compact desktop-style power supply measuring 79 x 54 x 33 mm and weighing 0.235 kg. For 12V models, the output cable length is specified as 180 cm using UL1185 16AWG cable.
