Overview

GSM36U48-P1J is the 48V output model of this series: rated current 0.75A, typical efficiency 88%. Type P1J: Plug for standard model, 2.1φ x 5.5φ x11mm, c+, tuning fork type.

GSM36U is a highly reliable, 36W wall-mounted style single-output green medical adaptor series. This product is equipped with a 2-pin (no FG) standard USA AC power plug, adopting the input range from 80VAC to 264VAC. The entire series supplies different output voltages between 5VDC and 48VDC that can satisfy the demands for various kinds of miniature medical devices. The circuitry design meets the international medical standards (2 × MOPP), having an ultra low leakage current (<50 μA), fitting the medical devices in direct electrical contact with the patients. With the efficiency up to 88% and the extreme low no-load power consumption below 0.1W, GSM36U is compliant with USA EISA 2007/DoE and Canada NRCan; the superme feature allows the adaptor to save the energy when it is either under the operating mode or the standby mode. The entire series utilizes the 94V-0 flame retardant plastic case, providing the double insulation that effectively prevents electrical shock. GSM36U is approved with the international medical safety certificates.

Test conditions and notes8

1. All parameters are specified at 115VAC 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. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

Can I use the GSM36U48-P1J for 48V industrial control hardware?

It can fit 48V DC control or embedded hardware that requires constant voltage and draws no more than 0.75A. This model is rated for 36W total output, so the connected 48V load needs to stay within that power and current limit.

Is the GSM36U48-P1J suitable for small 48V telecom or network equipment?

It can be suitable for 48V equipment that uses a constant voltage input and stays within 36W and 0.75A. The wide 80-264VAC input also helps when the AC source varies across regions or facilities.

Can this 48V power supply run embedded systems or test fixtures that need stable DC output?

Yes, if the embedded system or fixture is designed for 48V constant voltage power and its draw does not exceed 0.75A. The compact 79.0 x 54.0 x 33.0 mm size can also help where space is limited.

Is the GSM36U48-P1J a good fit for low-power 48V automation accessories?

It is appropriate for low-power 48V automation accessories when the total load stays within 36W. For selection, the key checks are that the device requires 48V constant voltage and that its current demand is at or below 0.75A.

Can the GSM36U48-P1J be used outdoors or in harsh plant conditions?

The provided specs list an operating temperature range of -25°C to +60°C, but they do not list an IP rating. That means the temperature capability is defined, but outdoor, washdown, or dust-tight suitability is not established by the stated specs.
