Test conditions and notes8
  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. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. Touch current was measured from primary input to DC output.
  7. 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. 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-100-24 for 24V PLC or industrial automation equipment?

Yes, if the equipment needs constant 24V DC and the total load stays within 4.5A. This unit is rated for 108W, which makes it suitable for 24V PLC-related loads, automation controls, or industrial electronics that match those output limits.

Is the MSP-100-24 a fit for 24V sensors, relays, or control modules?

It can be used for 24V control modules, relay assemblies, or sensor-powered systems when the combined demand does not exceed 108W. The output is fixed at 24V constant voltage with a maximum current of 4.5A.

Can this power supply support 24V embedded or IT equipment with global AC input requirements?

It is designed for 85-264VAC input, so it supports a wide AC input range for installations that need that flexibility. The DC output remains 24V constant voltage up to 4.5A, with 108W available to the connected load.

Can the MSP-100-24 be used in harsh indoor environments or exposed outdoor locations?

The specified operating temperature is -40°C to +60°C, which covers a broad environmental range for indoor equipment. No IP rating is listed in the provided specs, so exposed outdoor use is not established by this data alone.

What are the voltage and current differences across the MSP-100 family?

The MSP-100-24 version provides 24V, 4.5A, and 108W. The 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, 36V 2.9A 104.4W, and 48V 2.2A 105.6W.
