Test conditions and notes8
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  3. 3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
  4. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. Touch current was measured from primary input to DC output.
  7. 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).
  8. 8. The power supply is considered a component which will be installed into a final equipment. 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 )

FAQ

Can I use the MPM-45-48 for 48V telecom or network equipment?

It can be used for equipment that requires a constant 48V DC source and draws no more than 0.94A or 45.1W. That output profile fits many 48V IT, telecom, and communications power sections when the load stays within the rated current.

Is the MPM-45-48 a good fit for 48V industrial control or monitoring devices?

Yes, if the device expects 48V constant voltage input and its demand remains within 45.1W and 0.94A. The wide 80-264VAC input also supports use across a broad AC input range.

Can this model power 48V embedded systems or interface modules?

It is suitable for embedded or interface hardware that needs a regulated 48V output and does not exceed 0.94A. The compact 87.0 x 52.0 x 29.5 mm size can also help where internal space is limited.

Can the MPM-45-48 be used outdoors or in exposed environments?

The operating temperature range is -30°C to +80°C, so the temperature specification is broad. But the provided specs do not list an IP rating, so they do not claim weather, dust, or water ingress protection for exposed outdoor use.

What are the main differences between the MPM-45-48 and other MPM 45-series versions?

The 45-series outputs include 12V at 45W and 3.75A, 15V at 45W and 3A, 24V at 45.1W and 1.88A, 48V at 45.1W and 0.94A, and 5V at 40W and 8A. This non-ST 48V version measures 87.0 x 52.0 x 29.5 mm, while the ST 48V sibling keeps the same 45.1W, 48V, and 0.94A ratings in a 109.0 x 52.0 x 33.5 mm package.
