Test conditions and notes7
- 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 pin4,6) 0 ~ 8V or short.
- 7. 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-300-7.5 for a 7.5V industrial controller or legacy electronics load?
Yes, when the equipment specifically requires a constant voltage 7.5V DC source, this model provides up to 300W and 40A. It is best suited to industrial or embedded systems that are built around a 7.5V power rail rather than 5V, 12V, or 24V.
Is the MSP-300-7.5 a good fit for 7.5V test benches or lab fixtures in production environments?
It can be used where the fixture or device under test needs a stable 7.5V constant voltage input and the total load stays within 300W and 40A. That makes it relevant for production or service environments built around equipment with a defined 7.5V requirement.
Can the MSP-300-7.5 support 7.5V automation or embedded assemblies with higher current demand?
Yes, this unit is intended for loads that need 7.5V at higher current, with a rated output of 40A and 300W. The output can also be adjusted between 6.8V and 9V to match the assembly's exact rail requirement.
Is the MSP-300-7.5 suitable for outdoor or washdown locations?
The operating temperature range is -40°C to +70°C, with output derating required per the datasheet's derating curve. However, no IP rating is listed in the provided specs, so it should be treated as a power supply for protected environments rather than exposed outdoor or washdown areas.
What are the differences between the 7.5V MSP models?
This datasheet covers the MSP-300 series, in which the MSP-300-7.5 is the only 7.5V model, rated 300W and 40A with a 6.8-9V adjustment range. The other MSP-300 versions cover 3.3V to 48V, from 198W at 3.3V/60A up to 336W at 24V/14A and 48V/7A.
