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

What are the main output specifications of the Mean Well GST90A19-P1M power supply?

This model provides a regulated 19V DC output with a 90W power rating and a rated current of 4.74A. It is intended for equipment that requires a 19V desktop-style external power supply within that power range.

What types of equipment is the GST90A19-P1M typically used for?

The GST90A19-P1M is suited to 19V commercial and industrial devices that need up to 90W from an external AC-DC adaptor. Buyers commonly consider this type of supply for OEM equipment, embedded systems, displays, and other electronics where 19V DC is the required input.

Does this power supply support worldwide AC input?

Yes. The specified AC input range is 90 to 264VAC, which supports universal input across many regions. The unit also lists a typical power factor above 0.95 at 115VAC and a typical efficiency of 90%.

What DC plug does the GST90A19-P1M use?

The standard DC plug listed for this model is the P1M type, with dimensions of 2.5mm inner diameter by 5.5mm outer diameter and 11mm length. Buyers should confirm that their device requires this exact DC plug format in addition to matching the 19V output.

What protection features are included in this model?

This power supply includes overload, over-voltage, and over-temperature protection. The overload protection is specified as hiccup mode with auto-recovery, helping protect both the supply and connected equipment during abnormal operating conditions.

Is the GST90A19-P1M appropriate for demanding operating environments?

It is rated for operation across a wide temperature range of -30°C to +70°C, with output derating per the derating curve. The unit also carries major safety and EMC approvals, including UL62368-1 and Class B emissions, for commercial use.

What input and grounding class does this power supply use?

The GST90A19-P1M uses an IEC320-C14 AC inlet. The datasheet does not state a protection class; it specifies 2KVAC isolation from input to frame ground (FG), with the -V output not connected to AC FG.
