Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 5. Mounting holes M1 and M2 should be grounded for EMI purposes.
  6. 6. Heat Sink HS1,HS2 can not be shorted.
  7. 7. Touch current was measured from primary input to DC output.

FAQ

Can I use the MPS-45-24 for a small 24V PLC, sensor bank, or control circuit?

Yes, for 24V constant-voltage loads that stay within 45.6W and 1.9A, this model fits smaller automation and control applications. It is intended for lower-power 24V systems rather than equipment with a higher current demand.

Is the MPS-45-24 suitable for industrial networking or interface hardware that runs on 24V?

It can be suitable if the device requires 24V DC and draws no more than 1.9A. The wide 90-264VAC input is useful where the upstream AC source may vary across different facilities.

Can this 24V model power compact embedded or automation modules?

For compact 24V embedded or automation loads, the key limits are 45.6W total power and 1.9A output current. As long as the load matches the 24V constant-voltage output and stays within those ratings, it is within the published spec.

Is the MPS-45-24 OK for outdoor enclosures or unprotected plant areas?

The listed environmental spec is -10°C to +60°C operating temperature, but no IP rating is provided. That means the supplied data does not confirm suitability for rain, spray, or other exposed outdoor conditions.

How does the MPS-45-24 differ from the other MPS series options?

This model is 45.6W at 24V and 1.9A. The other models on the MPS-45 sheet are MPS-45-3.3 26.4W 3.3V 8A, MPS-45-5 40W 5V 8A, MPS-45-7.5 40.5W 7.5V 5.4A, MPS-45-12 44.4W 12V 3.7A, MPS-45-13.5 44.55W 13.5V 3.3A, MPS-45-15 45W 15V 3A, MPS-45-27 45.9W 27V 1.7A, and MPS-45-48 48W 48V 1A. All share the 90-264VAC input, medical safety approvals and the 127*76*28mm size, so the main differences are output voltage, current and power.
