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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. 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.
6. No load power consumption<0.5W when RC- & RC+ (CN100 pin1,2) 0 ~ 0.8V or short.
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 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 )
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-450-7.5 for 7.5V industrial electronics or legacy control hardware?

Yes, this model supplies constant 7.5V output at up to 60A with a 450W rating. That suits industrial or legacy DC equipment specifically designed around a 7.5V rail.

Is the MSP-450-7.5 suitable for embedded test systems that require a regulated 7.5V bus?

It can be, as long as the equipment is intended for a constant voltage 7.5V source and the load stays within 60A and 450W. The high available current is useful for larger embedded test platforms or multi-board fixtures.

Would this 7.5V power supply work for control panels or automation assemblies with uncommon DC voltage requirements?

Yes, the MSP-450-7.5 is relevant when the assembly is built for 7.5V DC rather than more common 5V, 12V, or 24V rails. Its output can be adjusted from 6.8V to 9V and delivers up to 60A for heavier assemblies.

Can the MSP-450-7.5 be used in electronics manufacturing fixtures that need high current at 7.5V?

It is a practical option for manufacturing fixtures or burn-in equipment that require a fixed 7.5V output and substantial current capacity. The unit provides up to 60A from a single 7.5V constant voltage supply.

Is the MSP-450-7.5 suitable for indoor harsh-temperature environments or outdoor use?

The operating temperature range is -40°C to +70°C, with output derating required at higher ambient temperatures per the derating curve. No IP rating appears in the listed specs, so the product data does not classify it as outdoor-rated.
