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-45-27 for a 27V industrial control or instrumentation load?

Yes, if the equipment requires a constant 27V supply and the total draw stays within 45.9W and 1.7A. It is intended for lower-power 27V loads, not higher-current 27V systems.

Is this 27V model suitable for compact automation electronics or monitoring devices?

It can be suitable where the device specification calls for 27V DC constant voltage and the required current does not exceed 1.7A. The 90-264VAC input range also supports use in sites with varied AC input conditions.

Can the MPS-45-27 power small embedded equipment that needs 27V DC?

For small 27V embedded loads, this model is rated at 45.9W and 1.7A. It should only be selected when the equipment is designed for 27V rather than nearby voltages such as 24V.

Is the MPS-45-27 rated for outdoor use or damp environments?

The provided specs include an operating temperature range of -10°C to +60°C, but no IP rating is shown. Since no ingress-protection rating is listed, the product data here does not establish outdoor or wet-area suitability.

How does the MPS-45-27 compare to the rest of the MPS family?

This version is 45.9W at 27V and 1.7A. 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-45-24 45.6W 24V 1.9A, 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.
