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. 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 first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
  6. 6. Deating maybe needed under low input voltages, please check the derating curve for more detail.
  7. 7. 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-100-24 for a 24V PLC panel or industrial automation cabinet?

Yes, this model is suited to 24V DC control systems, PLC panels, and industrial automation cabinets when the load stays within 96W and 4A. Its DIN rail format makes it appropriate for enclosure-based power distribution.

Is the MDR-100-24 a good choice for building management systems that need a larger 24V DIN rail supply?

Yes, it fits building management and panel-mounted control systems that require 24V DC up to 4A. With 96W output and an output adjustable from 24V to 30V, it is the 24V model of the MDR-100 series.

Will the MDR-100-24 work in a control cabinet where DIN rail space still needs to be managed carefully?

Yes, it is a DIN rail power supply built for cabinet use, mounting on TS35/7.5 or TS35/15 rails. It measures 55 mm wide, 90 mm high and 100 mm deep, so it offers 96W output within 55 mm of rail width.

Can the MDR-100-24 support higher-demand 24V industrial loads better than smaller MDR models?

Yes, it provides 96W at 24V and up to 4A, with constant current limiting overload protection at 105 ~ 150% of rated power that recovers automatically. Ratings of smaller MDR models are not covered by this datasheet, so compare them using their own spec sheets.

What are the main differences between the MDR-100-24 and other MDR series models?

Within the MDR-100 series, the MDR-100-24 provides 96W at 24V and 4A with 86% typical efficiency. In the same frame, the MDR-100-12 is 90W at 12V and 7.5A (83%), while the MDR-100-48 is 96W at 48V and 2A (87%); all share the 55 x 90 x 100 mm housing and 85 ~ 264VAC input.

Can the MDR-100-24 be used in outdoor or washdown conditions?

The provided specs list an operating temperature range of -10°C to +60°C for environmental suitability. Because no IP rating is listed in the provided data, this model is better suited to use inside a control cabinet or enclosure than in a directly exposed environment.
