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-10-12 to power a 12V PLC or control panel device?

The MDR-10-12 is a 12V DIN rail power supply rated for 10W and 0.84A, so it can fit low-power 12V PLC and control panel loads that stay within those limits. Its 100.0 × 90.0 × 22.5 mm housing is ultra slim, which helps in narrow control cabinets. The wide 85-264VAC input also suits industrial panels that need standard AC input flexibility.

Is the MDR-10-12 suitable for industrial automation cabinets that need a slim DIN rail power supply?

Yes, this model is built as an ultra slim DIN rail power supply with a 22.5 mm width, which is useful when cabinet rail space is limited. It provides 12V output at up to 0.84A and 10W for low-power industrial automation devices. The DIN rail form factor makes it a practical fit for organized control cabinet layouts.

Can the MDR-10-12 be used in building management or control enclosure applications?

It can be used in building management and control enclosure systems that need a regulated 12V output and draw no more than 0.84A or 10W. The slim DIN rail design supports installation in compact building control panels. Its 85-264VAC input range also helps when the enclosure is fed from standard AC mains.

Can I use the MDR-10-12 for 12V sensors, relays, or interface modules in a control cabinet?

The MDR-10-12 can support 12V sensors, relays, or interface modules when the total load remains within 10W and 0.84A. It is designed for DIN rail mounting, so it fits well in control cabinets where narrow power supplies are preferred. Buyers should match the combined 12V load to the unit's available output before selecting it.

What is the difference between the MDR-10 series models and the larger MDR series options?

Within the MDR-10 series, the MDR-10-5 is 10W, 5V, 2A; the MDR-10-12 is 10W, 12V, 0.84A; the MDR-10-15 is 10W, 15V, 0.67A; and the MDR-10-24 is 10W, 24V, 0.42A. All four share the same 22.5 x 90 x 100 mm DIN rail housing and 85-264VAC input, so the main difference is output voltage and current. Larger MDR series models are covered by their own datasheets and should be checked there.

Is the MDR-10-12 appropriate for use in an enclosed industrial control cabinet?

Yes, this model is intended for DIN rail power distribution inside control cabinets or enclosures rather than exposed locations. Its operating temperature range is -20°C to +70°C, which supports a wide range of industrial cabinet conditions. The 0.15 kg weight and ultra slim body can also help in compact enclosure layouts.
