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. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  5. 5. 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 http://www.meanwell.com)
  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-120-48 for 48V industrial sensors or control devices?

Yes, it provides a constant 48V output up to 2.5A and 120W with a 25CFM fan, or 1.7A with convection cooling. It is suited to 48V industrial or automation equipment that requires a fixed 48V DC source and stays within those limits.

Is this a good fit for 48V telecom or network hardware that needs DC power?

It can be used for 48V DC equipment when the load does not exceed 2.5A or 120W with a 25CFM fan (1.7A by convection). Buyers should match the equipment's required voltage exactly to 48V, since this is a constant-voltage model.

Can the MPS-120-48 power a 48V automation subsystem inside a machine enclosure?

Yes, the 48V constant-voltage output and 120W rating (with a 25CFM fan; 1.7A by convection) make it appropriate for enclosed automation subsystems that run on 48V DC. Its input range of 90-264VAC also supports operation from a wide AC mains range.

Is this power supply intended for outdoor use?

The listed operating temperature is -20°C to +70°C (with derating per the derating curves), but no IP rating is provided in the specs. Based on the supplied data, temperature capability is defined, while exposure to rain, dust, or hose-down conditions is not.

What are the 48V options in the MPS series and where does this model fit?

On this spec sheet the MPS-120-48 is the only 48V model of the 120W medical series, rated 120W at 2.5A with a 25CFM fan or 1.7A by convection. The other single-output MPS-120 models are 3.3V, 5V, 12V, 15V and 24V.
