Overview
GSM18U07-P1J is the 7.5V output model of this series: rated current 2A, typical efficiency 83%.
GSM18U is a highly reliable, 18W 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 miniaturize 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, GSM18U is compliant with USA EISA 2007/DoE and Canada NRCan; 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. GSM18U 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 GSM18U07-P1J for a 7.5V embedded device or control peripheral?
This model provides constant 7.5V DC at up to 2A, with 15W total power. It is suitable for embedded devices, control peripherals, or compact electronics designed for a fixed 7.5V input within that load range.
Is the GSM18U07-P1J suitable for low-power automation interfaces that require 7.5V DC?
Yes, if the automation interface is specified for 7.5V constant-voltage input and draws no more than 2A. The 15W rating places it in the low-power category rather than for larger automation loads.
Can this 7.5V power supply be used for bench or test electronics with a fixed DC requirement?
It can be used for test or embedded electronics that require a regulated 7.5V DC source and stay within 15W. The wide 80-264VAC input range also makes it practical where AC source conditions may vary.
Is the GSM18U07-P1J meant for outdoor or exposed environments?
The specified operating temperature range is -25°C to +60°C. The provided product data does not include an IP rating, so it does not establish suitability for outdoor, wet, or dust-exposed conditions.
Is this a constant-voltage supply for devices that need exactly 7.5V DC?
Yes. The GSM18U07-P1J is a constant-voltage model with a fixed 7.5V output and 2A maximum output current, so it is intended for equipment designed around a regulated 7.5V DC input.
