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-120-15 for 15V industrial control or test equipment?

Yes, it is built for constant-voltage 15V applications and is rated for 8A with 120W total power with a 25CFM fan, or 5.3A with convection cooling. That makes it a fit for industrial control, bench, or test equipment that specifically requires 15V DC and stays within those limits. It is not interchangeable with 12V or 24V loads that need a different nominal output.

Is the MPS-120-15 suitable for embedded systems or instrumentation that need 15V DC?

It can work for embedded or instrumentation loads designed around a 15V constant-voltage input. The available output is 8A with a 25CFM fan (5.3A by convection), with 120W total capacity, so it suits moderate-power 15V electronics rather than higher-current 200W-class systems. The 90-264VAC input is also useful when equipment may be deployed across different mains ranges.

Can the MPS-120-15 be used for 15V automation accessories inside a machine enclosure?

It can be used where the machine or control assembly needs a regulated 15V source and the total load remains within 8A and 120W with a 25CFM fan, or 5.3A with convection cooling. That makes it suitable for 15V automation accessories, sensors, or support electronics that are specified for constant-voltage operation. Buyers should size it to the actual 15V load, not just to the series name.

What are the main spec differences between the MPS-120-15 and related MPS models?

The listed MPS-120-15 is 120W at 15V and 8A. Nearby options include MPS-120-12 at 120W and 10A, MPS-120-24 at 120W and 5A, MPS-120-48 at 120W and 2.5A, MPS-120-5 at 110W and 22A, and MPS-120-3.3 at 79.2W and 24A. These ratings apply with a 25CFM fan; with convection cooling the MPS-120-15 is limited to 5.3A.

Can the MPS-120-15 handle wider ambient conditions, and is it okay outdoors?

Its rated operating temperature range is -20°C to +70°C with derating per the derating curves, so it supports a broad temperature band in controlled equipment conditions. The provided specs do not include an IP rating, which means outdoor exposure should not be assumed. It is better suited to protected indoor installations or enclosed systems.
