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 voltage. Please 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 )

What output does the Mean Well GST360A12-C8P provide?

This model provides a regulated 12V DC output with a 330W power rating. Its rated output current is 27.5A, making it suitable for higher-power 12V industrial and commercial equipment.

What type of connector and input inlet does the GST360A12-C8P use?

The GST360A12-C8P uses a MOLEX 8 pin connector (C8P, MOLEX 39-01-2080 equivalent) on the DC output side. On the AC input side, it has a 3-pole IEC320-C14 inlet with an earth (FG) connection.

What input voltage range does this power adaptor support?

This adaptor supports a universal input range of 85 to 264VAC, and it also accepts 120 to 370VDC. That wide range helps it fit into many global industrial power environments.

Is the GST360A12-C8P suitable for demanding industrial environments?

Yes, this model is designed for industrial use and operates over a wide temperature range from -30°C to +70°C, subject to the output derating curve. It also includes protection for overload, over voltage, and over temperature conditions.

What efficiency and compliance features does this model offer?

The GST360A12-C8P has a typical efficiency of 91% and a typical power factor above 0.95 at 230VAC (above 0.98 at 115VAC). It is approved to UL62368-1, CSA C22.2 No.62368-1, BS EN/EN62368-1, AS/NZS 62368.1 and other international safety standards.

What kinds of applications is this 12V 330W adaptor typically used for?

This model is typically considered for 12V equipment that needs a high-current desktop-style industrial AC-DC adaptor. Buyers often look at it for commercial or industrial devices that require a 12V supply, up to 27.5A output, and a MOLEX 8 pin connector format.

What physical size and cable details should buyers know?

The adaptor measures 220 x 95 x 46 mm and weighs 1.4 kg. It includes a 100 cm output cable specified as UL2464, 16AWG x 6C.
