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 http://www.meanwell.com)
5. Mounting holes M1 and M2 should be grounded for EMI purposes.
6. Heat Sink HS1,HS2 can not be shorted.
7. Touch current was measured from primary input to DC output.

FAQ

Can I use the MPS-45-7.5 for a 7.5V control board or embedded device?

Yes, if the equipment is designed for constant 7.5V DC and requires no more than 5.4A or 40.5W. This makes it suitable for 7.5V control electronics, embedded assemblies, and specialty industrial devices built around that voltage. The output should be matched exactly to the load's rated input requirement.

Is this power supply a fit for 7.5V test or measurement equipment?

It can be appropriate for test, measurement, or monitoring equipment that calls for a regulated 7.5V constant-voltage source. The unit is rated for 5.4A and 40.5W, which is useful for moderate-power 7.5V electronics. It should not be selected for loads that need a different DC voltage.

Can the MPS-45-7.5 power several 7.5V modules in one enclosure?

It can, as long as the combined load remains within 5.4A and 40.5W. That can suit multi-board embedded or instrumentation assemblies using a shared 7.5V bus. Because it is a constant-voltage design, all connected loads need to be rated for 7.5V DC.

Is the MPS-45-7.5 suitable for outdoor locations or unsealed equipment?

The operating temperature is specified from -10°C to +60°C, but the specs do not list an IP rating. Without a stated ingress-protection rating, outdoor or exposed use is not confirmed by the product data. It is better aligned with protected indoor installations or enclosed equipment.

How does the MPS-45-7.5 compare with other 7.5V models in the MPS series?

The MPS-45 sheet lists only one 7.5V model: the MPS-45-7.5, rated at 40.5W and 5.4A. The other MPS-45 versions run from 3.3V to 48V, with the 5V model at 40W and 8A and the 12V model at 44.4W and 3.7A as the nearest voltages. All share the same 90-264VAC input and 127*76*28mm size, so the difference is output voltage and current.
