Overview

GEM12I48-P1J is the 48V output model of this series: rated current 0.25A, typical efficiency 87%.

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.

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 GEM12I48-P1J for a small 48V telecom or communications device?

It can suit compact 48V equipment that requires constant-voltage input and draws no more than 0.25A. The total rated output is 12W, so it is intended for lower-power 48V loads.

Is the GEM12I48-P1J suitable for embedded control hardware that runs on 48V DC?

Yes, if the hardware specifically calls for 48V constant-voltage power. This model delivers up to 0.25A at 48V, with 12W total output capacity.

Can this 48V adapter power a low-power industrial network accessory?

It is appropriate for low-power 48V accessories where a fixed constant-voltage source is required. Buyers should match the device to the 48V output and keep demand within 0.25A and 12W.

Is the GEM12I48-P1J suitable for outdoor use?

It is rated for -20°C to +70°C operation, with derating at higher temperatures per the derating curve. The enclosure is rated IP21, so it is not suited to outdoor installation; use it indoors.

Is this the right type of supply for a 48V constant-voltage load?

Yes, this model is specified as constant voltage rather than constant current. Its rated output is 48V at 0.25A, with 12W maximum power for compatible loads.
