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-100-48 for a 48V industrial control or automation device?
Yes, if the device requires a 48V constant-voltage supply and its load stays within 100.8W and 2.1A. That makes it a fit for industrial and automation equipment designed around a 48V DC input.
Is this power supply suitable for 48V embedded or communications hardware?
It can be suitable for embedded or communications hardware that specifies 48V DC input and draws no more than 2.1A. The unit provides constant-voltage output at 48V with a total output rating of 100.8W.
Can I use this 48V power supply in a compact equipment enclosure?
It can suit space-limited equipment, as the unit measures 222.0 x 62.0 x 32.0 mm and weighs 0.45 kg. For OEM panels or embedded enclosures, that size can help when the system needs 48V at up to 100.8W.
Is the LPS-100-48 suitable for outdoor or harsh-environment use?
The provided specs show an operating temperature range of -10°C to +60°C, but they do not list an IP rating. That means temperature suitability is defined, while indoor or outdoor enclosure suitability is not established by the provided specs alone.
How does the LPS-100-48 compare with other Mean Well LPS models in this group?
Within the LPS-100 series, the LPS-100-48 is the 48V option at 100.8W and 2.1A. The other outputs are 3.3V at 66W, 5V at 100W, 7.5V at 99.75W, 12V at 100.8W, 13.5V at 101.25W, 15V at 100.5W, 24V at 100.8W, and 27V at 102.6W.
