Mean Well GSM90B48-P1M Power Supply 90W 48V 1.87A
Overview
GSM90B48-P1M is the 48V output model of this series: rated current 1.87A, typical efficiency 91%.
GSM90B is a highly reliable, 90W desktop style single-output green medical adaptor series. This product is equipped with a 2-pin (no FG) standard IEC320-C8 power plug, adopting the input range from 80VAC to 264VAC. The entire series supplies different output voltages between 12VDC and 48VDC that can satisfy the demands for various kinds of medical electrical devices. The circuitry design meets the international medical standards (2*MOPP), having an ultra low leakage current (<100 μA), fitting the medical devices in direct electrical contact with the patients. With the efficiency up to 91% and the extremely low no-load power consumption below 0.15W, GSM90B is compliant with USA EISA 2007/DoE, Canada NRCan, Australia and New Zealand MEPS, EU ErP,and meet Code of Conduct (CoC) Version 5. The supreme 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. GSM90B is approved with the international medical safety certificates.

Test conditions and notes9
- 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. 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 ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 9. 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 GSM90B48-P1M for 48V automation or motion-control accessories?
Yes, it can power 48V automation accessories that need constant-voltage output and stay within 1.87A and 90W. It is intended for applications that specifically call for a regulated 48V DC source.
Is this model suitable for 48V industrial communication or control devices?
It can be suitable for 48V industrial communication or control devices that accept constant 48V DC input. The load must remain within the rated 1.87A output current and 90W maximum power.
Can the GSM90B48-P1M power 48V embedded systems or instrumentation?
Yes, it is a fit for 48V embedded systems or instrumentation that are designed around constant-voltage operation. The electrical check is simple: the connected equipment must not exceed 48V, 1.87A, and 90W on the output side.
Would this power supply work for 48V telecom support equipment?
It can work for 48V telecom support equipment when the device requires constant 48V DC and the draw is within 1.87A. The 80-264VAC input range is also useful where incoming AC supply conditions vary.
Is the GSM90B48-P1M appropriate for outdoor deployment?
The unit is specified for operation from -30°C to +70°C, which covers a wide temperature range. However, no IP rating appears in the provided specifications, so the product data does not confirm suitability for outdoor or wet-environment exposure.
What kind of 48V load is this supply sized for?
It is sized for constant-voltage 48V loads up to 1.87A, with a total output limit of 90W. That makes it appropriate when the full connected load stays at or below those stated ratings.
