Overview

GSM12E48-P1J is the 48V output model of this series: rated current 0.25A, typical efficiency 87%. Type P1J: Plug for standard model, 2.1ψ×5.5ψ×11mm, C+ tuning fork type.

GSM12E 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 the standard 2-pin European plug. GSM12E 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 (<0.1W for 18V/48V), GSM12E is compliant with EU ErP and meet CoC version 5 (Except for 18V/48V). 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 GSM12E48-P1J to power a small 48V industrial sensor or control accessory?

Yes, this model is intended for constant-voltage 48V loads up to 0.25A, with a total output of 12W. It fits low-power industrial or automation devices that specifically require 48V DC and stay within those limits.

Is this 48V adapter appropriate for embedded or telecom interface modules that need 48V DC?

It can be a fit for embedded or interface equipment designed for constant-voltage 48V input. The key limits are 12W maximum output and 0.25A output current, so the connected module must be rated within both.

Can this power supply be used for a low-power 48V building automation device?

It is suitable for building automation or control devices that require a regulated 48V constant-voltage source. This unit provides 48V at up to 0.25A, so it is best for lower-power devices within the 12W rating.

How do I know if a 48V device is compatible with the GSM12E48-P1J?

The device should require constant-voltage 48V DC and draw no more than 0.25A or 12W. If its requirement exceeds 0.25A or 12W, this model is undersized.

Is the GSM12E48-P1J suitable for indoor or outdoor use?

The listed operating temperature range is -20°C to +70°C (with derating at higher temperatures), which supports a wide range of indoor equipment environments. The unit is rated IP22, which does not make it suitable for outdoor or washdown use.
