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-120-5 for a 5V PLC accessory or industrial logic load?

Yes, it supplies a constant 5V output up to 22A (110W) with a 25CFM fan, or up to 14.7A with convection cooling. That makes it suitable for 5V industrial logic assemblies, controller accessories, and other 5V DC loads that need higher current capacity.

Is this power supply appropriate for 5V embedded computing or single-board systems?

It can be a fit for 5V embedded systems when the total demand stays within 14.7A with convection cooling, or 22A and 110W with a 25CFM fan. The constant-voltage design is intended for loads that require a fixed 5V DC source rather than a constant-current output.

Can the MPS-120-5 support a bank of 5V automation electronics in one enclosure?

Yes, its 22A output capacity with a 25CFM fan (14.7A by convection) is useful where several 5V automation or control loads share one power source. The 90-264VAC input range also supports operation across common global AC input ranges.

Is the MPS-120-5 suitable for harsh indoor or outdoor conditions?

The provided specifications give an operating temperature range of -20°C to +70°C (with derating per the derating curves), but they do not list an IP rating. That supports temperature evaluation, but it does not confirm suitability for outdoor, wet, or dust-exposed environments.

How does this compare with the other 5V MPS power supplies?

On this spec sheet the MPS-120-5 is the only single-output 5V model of the 120W medical series; the other MPS-120 models are 3.3V, 12V, 15V, 24V and 48V. The multi-output MPD-120, MPT-120 and MPQ-120 models also carry a 5V output rated 10A alongside their other outputs.
