Test conditions and notes8
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 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. Tolerance : includes set up tolerance, line regulation and load regulation.
- 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 6. Touch current was measured from primary input to DC output.
- 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. 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-90-48 for equipment built around a 48V DC bus?
This is a constant voltage 48V supply rated for 90.2W with 1.88A output current. That makes it appropriate for equipment specifically designed for a 48V DC input and drawing no more than 1.88A. It is a better match for 48V systems than 12V, 15V, or 24V variants in the same family.
Is the MPM-90-48 suitable for compact communications or industrial electronics that require 48V input?
It can fit compact communications, embedded, or industrial electronics when the device requires regulated 48V constant voltage power. The output is limited to 90.2W and 1.88A, and the unit itself is compact at 87.0 x 52.0 x 29.5 mm. Those specs are useful where space is tight and the equipment is designed around a 48V rail.
Would this 48V model make sense for higher-power embedded or control assemblies?
This model provides up to 90.2W and 1.88A on a 48V bus, with a 99.2W peak allowed for up to 10 seconds. That can be useful for embedded or control assemblies whose demand fits within those ratings. The application still needs a 48V constant voltage input requirement.
Can the MPM-90-48 be used in cold or hot operating environments?
The specified operating temperature range is -30C to +80C (with derating per the derating curve), which covers a broad range of equipment environments. No IP rating is provided in the specs shown here. Because of that, the data supports temperature suitability review but does not confirm outdoor or water-exposed use.
How does the MPM-90-48 compare with the other 48V MPM models?
In the MPM-90 series the 48V models are the MPM-90-48 and the MPM-90-48ST at 90.2W and 1.88A. The MPM-90-48 shares the same electrical rating as the 90-48ST variant, but it is the PCB mounting style with published dimensions of 87.0 x 52.0 x 29.5 mm and a weight of 0.197 kg, versus 109.0 x 52.0 x 33.5 mm and 0.219 kg for the ST.
