Frequently Asked Questions
What are the main output specifications of the Mean Well GSM36B12-P1J?
The GSM36B12-P1J is a 36W desktop AC/DC power supply 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 a fully enclosed plastic case and built-in protections for short circuit, overload, and over voltage.
What makes the GSM36B12-P1J different from a standard consumer power adaptor?
This model is positioned as a higher-spec desktop adaptor because it combines medical approvals, very low leakage current, and low no-load power consumption below 0.1W. It also offers up to 88% efficiency, Class II construction, and a 100% full-load burn-in test for added reliability.
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.
