Overview

GSM36B05-P1J is the 5V output model of this series: rated current 4.5A, typical efficiency 80%.

GSM36B is a highly reliable, 36W desktop style single-output green medical adaptor series. This product is equipped with a 2-pin (no FG) standard IEC320-C8 power plug, adopting the input range from 80VAC to 264VAC. The entire series supplies different output voltages between 5VDC and 48VDC that can satisfiy the demands for various kinds of minature 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, GSM36B is compliant with USA EISA 2007/DoE, Canada NRCan, Australia and New Zealand MEPS, 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. GSM36B 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

What are the main output specifications of the Mean Well GSM36B05-P1J?

The GSM36B05-P1J is a 22.5W AC-DC medical adaptor with a regulated 5V DC output rated at 4.5A. It is designed for applications that need a stable low-voltage supply from a compact external adapter. This model uses the P1J standard DC plug.

Is the GSM36B05-P1J suitable for medical equipment applications?

Yes, this model is part of Mean Well's medical-approved GSM series and includes 2 x MOPP isolation between primary and secondary. It is approved to medical safety standards including ANSI/AAMI ES60601-1 and EN60601-1-11. Its low leakage current of less than 50uA also supports use in medical-related environments.

What input voltage range does the GSM36B05-P1J support?

This power supply accepts a universal AC input range of 80 to 264VAC, as well as 113 to 370VDC. That wide input range makes it suitable for use across different regions and power systems. It is built as a full-range external adapter.

Can this power supply be used in demanding operating environments?

The GSM36B05-P1J is rated for operation from -25°C to +60°C (refer to the derating curve), which makes it suitable for a broad range of indoor equipment environments. It also includes built-in overload protection (hiccup mode, auto-recovery) and over voltage protection. These features support reliable operation in commercial and industrial use cases.

How efficient is the Mean Well GSM36B05-P1J, and does it waste power at no load?

This model has a typical efficiency of 80%, which helps reduce excess heat and energy loss during operation. The datasheet does not specify a no-load power consumption figure for it. A power LED shows when the unit is on.

What plug type and cable details come with the GSM36B05-P1J?

The standard output plug is the P1J type, specified as 2.1mm x 5.5mm x 11mm with center positive polarity. For 5V models, the output cable length is 120cm and uses UL1185 16AWG cable. Buyers should confirm the plug format matches their device's required input jack.
