Overview
GEM18I18-P1J is the 18V output model of this series: rated current 1A, typical efficiency 84%.
GEM18I is a highly reliable, 18W 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. GEM18I 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, GEM18I 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 electric hazard.

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.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 GEM18I18-P1J for an 18V industrial control or monitoring device?
Yes, if the device requires constant 18V DC and its load stays within 1A and 18W. This fits lower-power 18V control, sensing, or monitoring equipment rather than higher-demand loads.
Is this 18V power supply suitable for embedded equipment or compact electronics?
The unit provides a constant 18V output with up to 1A available and 18W total power. It can be used with compact 18V electronics that are designed for constant-voltage input within that rating.
Can GEM18I18-P1J power small automation peripherals that need 18V DC?
It can support small 18V automation peripherals as long as the total demand does not exceed 1A or 18W. The product is a constant-voltage design, so it should only be paired with loads specified for constant 18V input.
Is GEM18I18-P1J suitable for cold or warm indoor operating conditions?
The published operating temperature range is -20°C to +50°C, with output derating per the derating curve. The unit is rated IP21, so the specs cover indoor use but not outdoor or liquid-exposure protection.
Does the wide AC input range help for equipment used across different sites?
Yes, the input range is 80-264VAC, which supports a broad span of AC supply conditions. That is useful when the same 18V / 1A / 18W output model is deployed in more than one mains-voltage environment.
