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-45-13.5 for a 13.5V communications or control device?

It is intended for loads that require a constant 13.5V output and stay within 44.55W and 3.3A. That makes it a fit for lower-power 13.5V equipment rather than systems that need a higher current margin.

Is this power supply suitable for 13.5V battery-backed control electronics or alarm-related hardware?

It can be used where the equipment specifically requires 13.5V constant voltage and the load remains at or below 3.3A and 44.55W. The answer depends on matching the device requirement to the published 13.5V output rather than using a nearby voltage model.

Can the MPS-45-13.5 power a compact embedded or industrial monitoring system?

Yes, for compact 13.5V monitoring or embedded loads within 44.55W, this model provides a constant-voltage output with a wide 90-264VAC input range. It is better suited to modest 13.5V loads than higher-power systems.

Is the MPS-45-13.5 meant for outdoor cabinets or exposed environments?

The listed operating temperature is -10°C to +60°C, but no IP rating is shown in the provided specs. Without an IP rating in the product data, outdoor exposure or wet-location suitability is not established here.

What are the main differences between the MPS-45-13.5 and other MPS family models?

This model is 44.55W at 13.5V and 3.3A. 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-45-15 45W 15V 3A, MPS-45-24 45.6W 24V 1.9A, 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.
