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 GSM120A15-R7B for a 15V industrial control or automation load?

This supply provides constant-voltage 15V output with a 105W rating and up to 7A of output current. It is suitable for larger 15V control, automation, and embedded loads that need more power than a small adapter can provide.

Is this a good fit for 15V embedded equipment, test systems, or OEM assemblies?

It can be a strong fit for 15V equipment that requires a regulated constant-voltage source and stays within 7A. With 105W available, it supports more demanding 15V OEM assemblies and test systems than low-wattage desktop supplies.

Can this model power a 15V communications, monitoring, or industrial computing device?

Yes, if the device is specified for 15V input and its total demand does not exceed 105W. The wide 80-264VAC input also helps when the equipment may be deployed across different AC mains conditions.

How do I know if my 15V load is sized correctly for this power supply?

Your load should require 15V constant-voltage input and draw no more than 7A or 105W. If the equipment exceeds either of those output limits, this model is not the correct size.

Is the GSM120A15-R7B suitable for harsh temperature conditions?

The published operating temperature range is -30°C to +70°C, with output derating at higher ambient temperatures per the derating curve, which supports use in much broader ambient conditions than supplies rated only from 0°C to +50°C. No IP rating is listed in the provided specs, so indoor or outdoor exposure should be evaluated separately from the temperature range.
