Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 5. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets 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 )
- 6. 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).

FAQ
Can I use the LPS-50-12 for a 12V industrial controller or automation accessory?
Yes, if the equipment requires 12V constant voltage and the load stays within 50.4W and 4.2A. That makes it suitable for lower-power industrial control and automation devices built for a 12V DC input.
Is this a good power supply for 12V embedded systems or small HMI hardware?
It can be a fit for embedded systems or compact HMI hardware that run on 12V DC and need no more than 4.2A. The 50.4W rating makes it best suited to lower-power 12V loads.
Can the LPS-50-12 be used where a very low-profile power supply is needed?
Yes, the dimensions are 195.0 x 55.0 x 23.0 mm and the features call out a 23mm thickness and low-profile form factor. That makes it practical for compact 12V equipment where enclosure height is limited.
Is the LPS-50-12 appropriate for colder or hotter indoor environments?
The specified operating temperature range is -20°C to +70°C, with output derating at higher ambient temperatures per the derating curve. The provided specs do not include an IP rating, so temperature capability is stated but outdoor protection level is not.
