Overview
GSM12U12-P1J is the 12V output model of this series: rated current 1A, typical efficiency 82.5%.
GSM12U is a highly reliable, 12W wall-mounted style single-output green medical adaptor series, which is compact and convient for carry. This product is equipped with the standard 2-pin U.S. plug. GSM12U is a class Ⅱ power unit (no FG), accepting the input range from 80VAC to 264VAC that it can satisfy the demands for various types of medical electrical devices. The circuitry design meets the international medical standards (2*MOPP), having an ultra low leakage current (<100μA), fitting the medical devices in direct electrical contact with the patients. With the working effiiciency up to 87% and the extremely low no-load power consumption below 0.075W (<0.1W for 18V/48V), GSM12U is compliant with the latest USA energy regulation EISA 2007/DoE(Level Ⅵ). The supreme feature allows the adaptor to save the energy when it is under either the operating mode or the standby mode. The entire series is approved for international safety regulations; moreover, it adopts the 94V-0 flame retadant plastic case that it can effeclively prevent users from electric hazarad.

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.Load regulation is measured from 10% to 100% rated load.
- 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 http://www.meanwell.com)

FAQ
Can I use the GSM12U12-P1J for a 12V automation controller or small PLC accessory?
Yes, if the device requires constant-voltage 12V DC and draws no more than 1A or 12W. That makes it relevant for lower-power automation and control accessories built around a 12V input.
Is this 12V adapter suitable for embedded or IT equipment that runs on 12V DC?
It can be used with embedded or IT hardware designed for a regulated 12V constant-voltage source. The supported output is 12V at up to 1A, with 12W maximum power.
Can the GSM12U12-P1J power a compact 12V industrial sensor hub or interface unit?
It is suitable for compact 12V DC equipment that stays within the rated output. The load must be a constant-voltage 12V device and must not exceed 1A or 12W.
How do I size a 12V load for this power supply?
The load should require 12V DC constant voltage and remain at or below 1A output current. The total power also needs to stay within the 12W rating.
Is the GSM12U12-P1J appropriate for indoor equipment with variable ambient temperatures?
Its stated operating temperature range is -20°C to +70°C, with load derating at higher ambient temperatures, which covers a broad indoor operating envelope. It is rated IP22, so it is not intended for outdoor use without additional protection.
