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 0.1 μF & 47 μF 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 )

FAQ

What are the main output specifications of the Mean Well GST360B12-C8P?

The GST360B12-C8P is a 330W AC-DC industrial adaptor with a regulated 12V DC output. It is rated for up to 27.5A continuous current and supports 415W peak power for 3 seconds.

What kind of applications is this 12V power adaptor suited for?

This model is intended for industrial or commercial equipment that needs a high-power 12V DC supply with up to 27.5A available output. It is particularly relevant where a MOLEX 8 pin connector and an external adaptor format are required.

What input voltage range does the GST360B12-C8P support?

The adaptor accepts universal AC input from 85 to 264VAC and also supports 120 to 370VDC input. That full-range input makes it suitable for use across many regional power environments without changing the power unit itself.

What output connector does this model use?

The GST360B12-C8P uses a C8P MOLEX 8 pin connector as its standard DC plug. It also includes a 100cm output cable specified as UL2464, 16AWG x 6C.

How does this model perform in demanding environments?

The specified operating temperature range is -30°C to +70°C, subject to the output derating curve. It is also rated for operating altitudes up to 5000 meters and 10 to 500Hz, 2G vibration, which can be beneficial in industrial applications.

What protection and compliance features does the GST360B12-C8P include?

This adaptor includes overload (hiccup mode, auto-recovery), over voltage, and over temperature protection. Its typical power factor is above 0.95 at 230VAC, and it is listed with multiple safety and EMC approvals including UL62368-1, BS EN/EN62368-1, BS EN/EN55032 Class B, and FCC Part 15/CISPR22 Class B.

What are the physical size and weight of this power adaptor?

The GST360B12-C8P measures 220 x 95 x 46 mm and weighs 1.4 kg. Mean Well specifies an MTBF of 2057.2K hours min. (Telcordia SR-332).
