Overview

GSM18U05-P1J is the 5V output model of this series: rated current 3A, typical efficiency 80%.

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. 1. All parameters are specified at 115VAC 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 voltage. Please check the derating curve for more details.
  8. 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 GSM18U05-P1J for a 5V single-board computer or embedded controller?

This model supplies constant 5V DC at up to 3A, with 15W total power. That makes it suitable for many 5V embedded controllers, single-board computers, or logic-based devices that require a regulated 5V source within that limit.

Is the GSM18U05-P1J a fit for 5V industrial interface electronics?

It can be used for low-power 5V industrial interface electronics, monitoring modules, or control boards that need constant-voltage input and draw no more than 3A. It is intended for electronics loads, not higher-power equipment outside the 15W rating.

Can this 5V power supply run USB-class or logic-level devices in IT equipment?

Yes, if the equipment is designed for a fixed 5V DC input and the total load stays within 15W. Its 3A rating is the highest output current in the GSM18U series, although this 5V version is rated at 15W rather than the 18W of the 9V to 48V models.

How does the GSM18U05-P1J handle indoor temperature conditions?

Its operating temperature range is -25°C to +60°C. The provided specs do not list an IP rating, so the data supports temperature suitability within that range but does not confirm outdoor or sealed-enclosure performance.

Is this model useful where space and weight matter in a compact device?

The housing measures 79.0 × 54.0 × 33.0 mm and the unit weighs 0.185 kg. That compact size can be helpful where a 5V supply is needed in a small equipment footprint.
