Test conditions and notes5
- 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 0.1uf & 47uf parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 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 http://www.meanwell.com)
- 5. When the input voltage is less than 40VAC, the SPS may exhibit degradation of performance. The final product manufacturers must re-confirm this deviation that does not affect basic safety or essential performance.

FAQ
Can I use the MPS-30-12 for a small 12V PLC, relay, or sensor circuit?
Yes, this model is a 12V constant-voltage supply rated for 30W and 2.5A. It is a reasonable fit for compact 12V PLC sections, relays, sensors, and other low-power automation loads that stay within that output limit.
Is the MPS-30-12 suitable for a 12V embedded controller or electronics enclosure?
It can be used for small 12V embedded systems, controller boards, and support electronics that need a constant 12V DC source. The smaller 101.6 × 65.8 × 23.5 mm size also helps where cabinet space is limited.
Would the MPS-30-12 work for light-duty industrial instrumentation at 12V?
Yes, it fits low-power 12V instrumentation, signal-conditioning modules, and monitoring devices if the total demand remains within 30W and 2.5A. It is better suited to lighter 12V loads than higher-power control assemblies.
Can this power supply support a compact 12V bench or test fixture?
It can support a small 12V bench fixture or validation setup that needs a constant-voltage source and modest output. The 88-264VAC input also supports use across a wide AC input range.
Is the MPS-30-12 suitable for outdoor use or washdown areas?
The operating temperature range is -10°C to +60°C, but no IP rating is provided in the specs. That means it is better suited to indoor or protected enclosure use rather than exposed outdoor or washdown environments.
