Test conditions and notes8

1. All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
2. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
3. Tolerance: includes set up tolerance, line regulation, load regulation.
4. Line regulation is measured from low line to high line at rated load.
5. 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.
6. Derating may be needed under low input voltage. Please check the derating curve for more details.
7. 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).
8. 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 GST120A15-R7B for a 15V industrial control device or embedded system?

Yes, this model is a constant voltage power supply with a 15V output and up to 7A available current. That makes it suitable for 15V industrial, embedded, or automation equipment that needs a regulated 15V source within a 105W power budget.

Is the GST120A15-R7B suitable for 15V HMI panels or small automation peripherals?

It can be a fit for 15V HMI panels or automation peripherals if the equipment is designed for constant voltage input at 15V. The unit provides up to 7A and 105W, so the connected load needs to stay within those limits.

Can this power supply run 15V lab, test, or monitoring equipment?

It is appropriate for 15V bench, monitoring, or test equipment that expects constant voltage DC input. The 15V output, 7A current capacity, and 85-264VAC input range make it usable across a wide range of AC mains conditions.

Will the GST120A15-R7B work in industrial environments with low or high ambient temperatures?

Its stated operating temperature range is -30°C to +70°C, which covers a broad range of indoor industrial conditions. Temperature capability is specified, but environmental sealing is not, so that does not by itself indicate suitability for wet or washdown areas.

Can I use the GST120A15-R7B outdoors or in exposed locations?

The product data provided here includes an operating temperature range of -30°C to +70°C, but it does not list an IP rating. Without an IP rating, these specs do not establish protection against rain, dust, or direct outdoor exposure.
