Overview

GSM40A48-P1J is the 48V output model of this series: rated current 0.84A, typical efficiency 91%.

GSM40A is a highly reliable, 40W single-output green medical adaptor series. This product is a class I power unit(with FG), equipped with a standard IEC320-C14 AC inlet and adopting the input range from 80VAC to 264VAC. The entire series supplies different models with output voltages between 5VDC and 48VDC that 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 efficiency up to 91% and the extremely low no-load power consumption below 0.15W, GSM40A 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.

Test conditions and notes9
  1. 1. All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
  2. 2. DC voltage: The output voltage set at point measure by plug terminal & 50% load.
  3. 3. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
  4. 4. Tolerance: includes set up tolerance, line regulation, load regulation.
  5. 5. Line regulation is measured from low line to high line at rated load.
  6. 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. 7. Derating may be needed under low input voltages. Pleas check the derating curve for more details.
  8. 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. 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 GSM40A48-P1J for 48V industrial sensors or field devices?

This model is a constant-voltage 48V power supply, so it fits equipment designed for a regulated 48V DC input. The connected load needs to stay within 0.84A and 40W.

Is this 48V power supply suitable for telecom or network equipment that runs on 48V DC?

It can be used with telecom or network hardware that specifically requires constant 48V DC input. Power draw must remain at or below 0.84A and 40W.

Will this work for embedded or automation controllers that require 48V DC?

Yes, if the controller is rated for constant 48V input. This unit provides up to 40W total output with a maximum current of 0.84A.

Can this power supply support a small 48V automation subsystem inside a control panel?

It is intended for constant-voltage 48V applications, which makes it a fit for compact automation loads that are specified for 48V DC. The available output is limited to 40W and 0.84A.

Is the GSM40A48-P1J suitable for outdoor or harsh-environment use?

The listed operating temperature is -30°C to +70°C, so the temperature range is broad. However, no IP rating is provided in the specs, so outdoor or washdown suitability is not confirmed by the product data shown here.
