Overview

GSM90B19-P1M is the 19V output model of this series: rated current 4.74A, typical efficiency 89%.

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 the GSM90B19-P1M power 19V industrial PCs or embedded computing hardware?

Yes, it is suitable for 19V devices that require constant-voltage DC input and stay within 90W and 4.74A. That makes it relevant for many embedded computing and industrial PC applications built around 19V power.

Is this a good option for 19V display, HMI, or kiosk systems?

It can be used for 19V display, HMI, or kiosk hardware when the product requires a steady 19V DC supply. The combined load must remain at or below 4.74A and 90W.

Can I use the GSM90B19-P1M for 19V networking or IT peripherals?

Yes, if the networking or IT peripheral is specified for constant 19V DC input, this supply can be a fit. Buyers should confirm the device does not exceed the 4.74A output current or 90W power rating.

Would this work for 19V monitoring or control terminals in automation environments?

It can support 19V monitoring or control terminals that need regulated constant-voltage power. The application match depends on the terminal being designed for 19V DC and drawing no more than 4.74A.

Can this power supply handle cold or hot operating conditions?

The listed operating temperature range is -30°C to +70°C, so it is specified for both low and high ambient temperatures within that span. Since no IP rating is provided, the specs do not establish outdoor weather exposure or water-ingress protection.

How should I check if this 19V supply matches my equipment?

Match it to equipment that requires constant 19V DC and draws 4.74A or less, with total power demand up to 90W. Those are the key electrical limits given in the product specs.
