Overview

GSM40B05-P1J is the 5V output model of this series: rated current 5A, typical efficiency 81%. Type P1J: Standard model,2.1 φ x5.5 φ x11mm,C+,tuning fork type.

GSM40B is a highly reliable, 40W 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 5VDC 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 (<50 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 0.1W, GSM40B 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. GSM40B 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 voltages. Pleas 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 GSM40B05-P1J for a 5V embedded controller or SBC?

Yes, this is a constant-voltage 5V power supply for equipment that requires regulated 5V DC input. The total load must stay within 5A and 25W.

Is this a good fit for 5V industrial interfaces or logic devices?

It fits 5V industrial or embedded electronics that are designed for constant 5V input. Output capacity is up to 5A, with 25W maximum power.

Can this power supply run a 5V automation module or compact HMI accessory?

It can power 5V automation accessories that need a constant-voltage source. The device load needs to remain at or below 5A and 25W.

Would this work for 5V test fixtures or control peripherals in an industrial setting?

It is suitable for 5V DC peripherals where a stable constant-voltage output is required. Capacity is limited to 25W total and 5A output current.

Can I use this 5V power supply in outdoor equipment cabinets?

The operating temperature range is -30°C to +70°C, which supports a wide temperature window. The specs do not list an IP rating, so outdoor exposure protection is not established by the published data.
