Test conditions and notes9

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. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
7. No load power consumption<0.8W when RC+ & RC- (CN100 pin3,4) 0 ~ 0.8V or short.
8. 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.
9. 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-600-3.3 for high-current 3.3V digital or logic systems?

Yes, this model is intended for constant 3.3V output and provides up to 396W and 120A. That makes it relevant for high-current 3.3V digital electronics, logic backplanes, or embedded hardware that needs a large 3.3V rail.

Is the MSP-600-3.3 suitable for 3.3V industrial computing or communication boards?

It can be a fit when those boards require a regulated 3.3V source and aggregate current is high. The 120A output rating is the key differentiator for systems built around heavy 3.3V distribution.

Can this power supply support 3.3V test racks or burn-in fixtures?

Yes, for test or validation environments that need constant 3.3V and significant current capacity. Its 396W total output and 120A maximum current allow it to serve dense 3.3V fixtures as long as the total load stays within those limits.

How do I size a system for the MSP-600-3.3?

The rating is 396W total at 3.3V, with up to 120A output current. It should only be used where the total 3.3V demand stays within both of those published limits.

Is the MSP-600-3.3 appropriate for outdoor or uncontrolled environments?

The unit is specified for operation from -40°C to +70°C, with output derating required at higher ambient temperatures (see the derating curve). But because no IP rating is listed, the published specs do not define it as an outdoor-rated or ingress-protected supply.

How does the MSP-600-3.3 compare to other 3.3V MSP models?

This spec sheet covers only the MSP-600 series, in which the MSP-600-3.3 is the 3.3V model, rated 396W and 120A. Ratings for 3.3V models of other MSP wattage classes are not given on this sheet, so compare against their own datasheets.
