Overview

GEM18I48-P1J is the 48V output model of this series: rated current 0.375A, typical efficiency 87%.

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.

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 GEM18I48-P1J for a low-power 48V industrial sensor or transmitter?

Yes, it can fit low-power 48V industrial devices that require constant voltage output. The supply provides 48V at up to 0.375A with 18W total capacity, so the connected load needs to stay within those limits.

Is this 48V adapter suitable for compact automation or access-control equipment?

It can be used for compact automation or control equipment when the device is designed for a 48V constant voltage source. The available output is 0.375A and 18W, so it is better suited to lower-power 48V loads than higher-draw equipment.

Can I use this power supply with embedded or networking hardware that runs on 48V DC?

It may be appropriate for embedded or networking hardware that specifies 48V DC input and does not exceed 0.375A. Its constant voltage operation and 80-264VAC input also make it practical where wide AC input compatibility is needed.

What is the difference between the GEM18I48-P1J and the other GEM18I48-P1J regional versions?

The sibling models are GEM18I48-P1J-欧套, GEM18I48-P1J-混套, GEM18I48-P1J-澳套, GEM18I48-P1J-美套, and GEM18I48-P1J-英套. This base model's listed electrical specs are 18W, 48V, 0.375A, 80-264VAC input, 75.5 × 39.1 × 56.2 mm dimensions, -20°C to +50°C operation, and TUV EN60601-1, ANSI/AAMI ES60601-1, CAN/CSA-C22 No. 60601-1, EAC and FCC Part 18 Class B approvals.

Is the GEM18I48-P1J suitable for outdoor or unprotected industrial environments?

The provided specs list an operating temperature of -20°C to +50°C (refer to the derating curve), and the adaptor is rated IP21. That means outdoor, washdown or unprotected exposed locations are not suitable for this unit.
