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. No load power consumption<0.5W when RC+ & RC- (CN100 pin1,2) 0 ~ 8V or short.
- 7. Touch current was measured from primary input to DC output.
- 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-200-3.3 for 3.3V logic rails in industrial embedded systems?
Yes, if the system requires constant-voltage 3.3V DC and the load fits within 132W and 40A. That combination is useful for high-current 3.3V logic or processor rails in embedded and industrial computing equipment.
Is the MSP-200-3.3 suitable for FPGA or processor boards that need high current at 3.3V?
This model is the highest-current option in the MSP-200 series, with 40A available at 3.3V and 132W total power. It is intended for equipment that specifically needs a regulated 3.3V source rather than 5V, 12V, or 24V.
Can this supply power multiple 3.3V control or communication modules from one source?
It can support multiple 3.3V loads when the combined demand stays within 132W and 40A. That makes it suitable for centralized 3.3V distribution in specialized embedded or digital control assemblies.
How does the MSP-200-3.3 compare with the other MSP-200 models?
The MSP-200 family spans 3.3V 132W 40A, 5V 175W 35A, 7.5V 200.3W 26.7A, 12V 200.4W 16.7A, 15V 201W 13.4A, 24V 201.6W 8.4A, 36V 205.2W 5.7A, and 48V 206.4W 4.3A. The 3.3V version is the lowest-voltage model in that group and delivers the highest current among the MSP-200 variants.
Is the MSP-200-3.3 appropriate for environments with wide temperature swings?
The operating temperature is specified from -40°C to +70°C, with output derating at higher ambient temperatures according to the derating curve. The provided specifications do not state an IP rating, so enclosure-level protection against dust or water is not defined here.
