Test conditions and notes10

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. Optional for 1.5KVAC with BF rated.
10. 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 GSM160A12-R7B to power a 12V industrial control cabinet with multiple devices?

Yes, this supply provides a 12V DC output at up to 11.5A, with a total power rating of 138W. Size the combined draw of all connected devices so it stays within 11.5A and 138W.

Is this power supply suitable for 12V automation equipment with higher current demand?

Yes, compared with lighter-duty units, this model supports a much higher 11.5A output at 12V. It fits automation equipment that needs regulated 12V DC and stays within the 138W maximum output.

Would the GSM160A12-R7B work for a 12V embedded system, IPC, or edge device with peripherals?

It can be a strong fit for 12V embedded or industrial computing equipment when the full system draw remains under 11.5A. The 80-264VAC input range also supports use in varied AC input environments.

Can this model be used for a larger 12V test bench or burn-in fixture?

Yes, its 138W capacity and 12V constant-voltage output make it suitable for more demanding 12V bench or validation loads. The larger 175.0 × 72.0 × 35.0 mm housing reflects that higher output class.

Is the GSM160A12-R7B suitable for cold or warm operating environments?

It has a specified operating temperature range of -30°C to +70°C, with output derating at higher ambient temperatures according to the derating curve. No IP rating is provided, so it is best used in protected environments or inside equipment that provides the necessary enclosure.

Can this supply be used in outdoor equipment if it is mounted inside a sealed enclosure?

The listed specs do not include an IP rating for the power supply itself, so outdoor suitability depends on the protection provided by the finished enclosure. Its -30°C to +70°C operating range supports use across a wide temperature span when environmental sealing is handled externally.
