Overview
GEM12I12-P1J is the 12V output model of this series: rated current 1A, typical efficiency 82.5%.
GEM12I is a highly reliable, 12W wall-mounted style single-output green medical adaptor series, which is compact and convenient for carry. This product is equipped with an interchangeable AC plug (4 types, including European type, USA type, U.K. type and Australian type) that makes it very suitable for businessmen to use in the major countries around the globe. GEM12I 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 efficiency up to 87% and the extremely low no-load power consumption below 0.075W, GEM12I is compliant with the latest USA energy regulation EISA 2007/DOE(Level Ⅵ) and EU ErP. 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 retardant plastic case that it can effectively prevent users from electrical hazard.

- 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 GEM12I12-P1J for a 12V industrial sensor hub or control module?
Yes, if the equipment needs constant 12V DC and draws no more than 1A. The 12W rating makes it appropriate for small 12V control electronics and sensor-related devices rather than higher-load 12V equipment.
Is this 12V power supply suitable for compact automation or embedded hardware?
It can be a fit for compact automation and embedded systems that are designed for constant 12V input. The load must remain within the 1A maximum output current and 12W total output rating.
Can this adapter power a 12V IT or communications accessory?
Yes, for low-power 12V accessories that require a constant-voltage supply and stay within 12W. That includes smaller IT and communications devices that do not exceed 1A current draw.
How do I know if my 12V device is the right size for the GEM12I12-P1J?
Check that the device requires 12V constant voltage and that its demand stays at or below 1A. Since the unit is rated for 12W, both the current and power limits must be respected.
How does the GEM12I12-P1J compare with the other GEM12I12 family options?
The GEM12I12-P1J is the cable-output version with the standard P1J DC plug (5.5/2.1mm). The AC input plug is interchangeable: AU, UK, EU, US and mixed plug sets are ordered separately (AC plug-AU2/UK2/EU2/US2/MIX2), so the electrical rating stays 12V, 1A, and 12W.
Is this model suitable for outdoor or variable-temperature locations?
It is rated for -20°C to +70°C ambient, with load derating at higher temperatures per the derating curve. The enclosure is rated IP21, so it is for indoor use, not outdoor or water-exposed locations.
