Test conditions and notes8
- 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. 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. If the input range 85V-89V, the output load is changed from 0A-rated load, There will be reduced 20V for 1second (LPS-100-24).
- 6. Mounting holes M1 and M2 should be grounded for EMI purposes.
- 7. Testing harmonic current at 90% load.
- 8. 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-100-27 for 27V industrial control or communications equipment?
Yes, if the equipment is designed for a 27V constant voltage input and draws no more than 3.8A. This model provides up to 102.6W, which fits many 27V control and communications loads within that current range.
Is the LPS-100-27 suitable for 27V embedded systems and interface hardware?
It can be suitable when the hardware expects a fixed 27V supply and stays below 102.6W total output. Its constant voltage operation is aligned with electronics that need a regulated DC rail rather than a constant current source.
Can this model power 27V automation modules in a compact cabinet?
Yes, for 27V automation modules whose combined load is within 3.8A. The 222.0 x 62.0 x 32.0 mm dimensions and 0.45 kg weight make it easier to consider in slimmer control assemblies.
Is the LPS-100-27 appropriate for equipment used across different AC input regions?
It accepts 88-132VAC / 176-264VAC input with automatic range switching, so it can support equipment builds that need the same DC output on both AC mains ranges. On the output side, it remains a 27V constant voltage supply rated for 3.8A.
What environments is the LPS-100-27 best matched for?
The provided operating temperature range is -10°C to +60°C, which defines the listed thermal conditions. Because no IP rating is provided in the specs, the safest fit from the available data is protected indoor equipment use rather than outdoor exposure.
