Test conditions and notes6
  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. 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 )
  5. 5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
  6. 6. 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).

FAQ

Can I use the MDR-10-24 for a PLC, sensor, or control circuit that requires 24V DC?

Yes, this model is designed for low-power 24V DC applications in PLC panels, industrial automation cabinets, and control enclosures as long as the load stays within 10W and 0.42A. Its DIN rail format makes it appropriate for standard control cabinet layouts.

Is the MDR-10-24 suitable for building management and panel-based control systems?

It is a practical choice for building management and control systems that use 24V DC and do not exceed 0.42A. The wide 85-264VAC input range also helps when the supply is being used across common AC mains conditions.

Does the MDR-10-24 make sense for compact DIN rail cabinets with limited space?

Yes, this unit is built with a 22.5 mm ultra slim profile, which is useful in narrow control cabinets and crowded DIN rail assemblies. Its full dimensions are 100.0 x 90.0 x 22.5 mm.

Can this 24V model be used for light industrial automation loads rather than larger field devices?

Yes, it fits light industrial automation loads that need 24V DC but only require up to 10W total power. If the application needs more than 0.42A, a power supply with a higher current rating would be needed.

What is the difference between the MDR-10-24 and related MDR series power supplies?

In the 10W group, the MDR-10-5 provides 5V at 2A, the MDR-10-12 provides 12V at 0.84A, the MDR-10-15 provides 15V at 0.67A, and the MDR-10-24 provides 24V at 0.42A. All four share the same 22.5 mm DIN rail housing and 85-264VAC input, so the main difference is output voltage and current.

Is the MDR-10-24 meant for outdoor or washdown environments?

The specified operating temperature is -20°C to +70°C, so temperature tolerance is broad for cabinet use. The provided specs do not list an IP rating, so this model is best suited for use inside a control cabinet or enclosure instead of an exposed environment.
