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

What are the main electrical ratings of the Mean Well GST90A48-P1M?

This model is a 90W AC/DC desktop power supply with a 48V DC output. It is rated for 1.87A output current. The input range is universal at 90 to 264VAC, which helps support global B2B equipment deployments.

What type of DC plug does the GST90A48-P1M use?

The GST90A48-P1M uses Mean Well's P1M plug style. The listed standard DC plug size is 2.5mm ID x 5.5mm OD x 11mm length. Buyers should confirm their device requires this exact plug format before ordering.

Is the GST90A48-P1M suitable for commercial or industrial equipment?

It is built for professional equipment use where a regulated 48V, 90W external power supply is required. This model includes overload, over-voltage, and over-temperature protection, along with 91% typical efficiency and a typical power factor above 0.95 at 115VAC. Those features make it a strong fit for B2B applications that need a branded external PSU.

How energy efficient is the Mean Well GST90A48-P1M?

This model has a typical efficiency of 91%, the highest in the GST90A series, and a typical power factor above 0.91 at 230VAC and 0.95 at 115VAC at full load. That makes it a good choice for businesses that want lower power losses and improved energy performance.

What safety and compliance standards does this power supply meet?

The GST90A48-P1M is listed with multiple safety approvals including UL62368-1, CSA C22.2 No.62368-1, TUV BS EN/EN62368-1, BSMI CNS15598-1, PSE J62368-1, CCC GB4943.1, and AS/NZS 62368.1. EMC compliance includes BS EN/EN55032 Class B, BS EN/EN61000-3-2/3, FCC Part 15/CISPR22 Class B, CNS15936, GB9254, and GB17625.1. These approvals are useful for OEM and business buyers working across regulated markets.

Can the GST90A48-P1M be used in demanding temperature environments?

The structured product data lists an operating temperature range of -30°C to 70°C, with output derating per the derating curve. That makes it suitable for many equipment environments where a standard consumer-grade adapter may not be sufficient. Final suitability still depends on the end equipment, enclosure, and overall thermal conditions.

What kind of AC input and enclosure design does this model use?

This power supply accepts a universal 90 to 264VAC input (or 127 to 370VDC) and uses an IEC320-C14 AC inlet, with the -V output not connected to AC FG. It has an LED power indicator, and the compact housing is listed at 145 x 60 x 32mm.
