Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. 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 )
  5. 5. 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 PS-05-12 for a 12V sensor, relay, or small control circuit?

Yes, this is a constant voltage 12V power supply rated for 0.45A and 5.4W. It is appropriate for small 12V control circuits, sensors, relays, and similar low-power industrial or automation loads within that output range.

Is the PS-05-12 suitable for low-power 12V embedded or instrumentation electronics?

Yes, its 12V regulated output and 5.4W capacity make it a fit for low-power embedded and instrumentation electronics that do not exceed 0.45A. It is intended for constant voltage applications rather than higher-power 12V equipment.

Can this model be used where AC input conditions may vary between sites?

Yes, the input range is 85-264VAC, which supports use across a wide span of AC input conditions. That can be useful for standardized low-power 12V equipment deployed in different facilities.

How does the PS-05-12 compare with the other low-power PS-05 models?

Within the PS-05 group listed here, PS-05-5 is 5W at 5V and 1A, PS-05-12 is 5.4W at 12V and 0.45A, PS-05-15 is 5.25W at 15V and 0.35A, PS-05-24 is 5.28W at 24V and 0.22A, and PS-05-48 is 5.28W at 48V and 0.11A. The main difference between them is the output voltage and corresponding current rating.

Is the PS-05-12 meant for outdoor installations or only indoor equipment?

The operating temperature range is -10°C to +60°C, which supports many indoor equipment environments. No IP rating is listed in the provided specs, so the product data does not state suitability for outdoor exposure or wet locations.
