Test conditions and notes7
- 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.Load regulation is measured from 0% to 100% rated load.
- 7.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 http://www.meanwell.com)

FAQ
Can I use the SGAS15B12-P1J for a 12V industrial sensor hub or control accessory?
Yes, if the load is designed for constant-voltage 12V DC and stays within 15W. This unit provides up to 1.25A at 12V, which suits lower-power control accessories and sensor-related electronics.
Is this 12V model suitable for small embedded systems or edge devices that run on 12V?
It can be used for embedded or edge hardware that expects a fixed 12V supply and does not exceed 1.25A. The constant-voltage output is intended for devices specified for 12V DC operation rather than variable or current-driven loads.
Can the SGAS15B12-P1J power a compact HMI, display, or panel accessory that needs 12V DC?
This model is appropriate for a compact 12V HMI or accessory when the device stays within the 15W and 1.25A limits. Its 80.0 × 39.0 × 27.7 mm dimensions can also be useful where internal space is tight.
Would this power supply work for low-power 12V automation or monitoring equipment?
Yes, for lower-power 12V automation equipment that needs a regulated constant-voltage source. The key compatibility checks are the 12V output, 15W power rating, and 1.25A maximum output current.
Is the SGAS15B12-P1J intended for outdoor use?
The available specs include an operating temperature range of -20°C to +70°C, but they do not list an IP rating. That means thermal limits are provided, while water and dust protection are not defined in the stated product data.
