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. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Touch current was measured from primary input to DC output.
7. 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.
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 MSP-100-48 for 48V telecom or network power applications?

Yes, if the equipment requires constant 48V DC and the total load does not exceed 2.2A. This model provides 105.6W, which fits lower-power 48V telecom, network, or IT hardware that matches those electrical limits.

Is the MSP-100-48 suitable for 48V industrial automation or control equipment?

It can be used for 48V automation or control devices that need a constant-voltage supply and remain within 105.6W. The maximum output is 48V at 2.2A, so the load has to fit that rating.

Can this model power 48V embedded or communications hardware in mixed AC environments?

Yes, the input range is 85-264VAC, which supports use where AC supply conditions vary. The DC output is fixed at 48V constant voltage with up to 2.2A available.

Is the MSP-100-48 rated for outdoor environments?

The unit is specified for operation from -40°C to +60°C, so the temperature range is broad. However, no IP rating is listed in the supplied specs, so outdoor suitability is not confirmed from this product data.

How does the MSP-100-48 compare to the other MSP-100 output options?

The MSP-100-48 is the highest-voltage MSP-100 version at 48V, 2.2A, and 105.6W. Other MSP-100 models are 3.3V 20A 66W, 5V 17A 85W, 7.5V 13.5A 101.3W, 12V 8.5A 102W, 15V 7A 105W, 24V 4.5A 108W, and 36V 2.9A 104.4W.
