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 first cold 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-60-48 for a 48V PLC cabinet or industrial control system?

Yes, it is intended for 48VDC applications and can supply up to 1.25A with a 60W rating. That makes it a fit for 48V industrial control, PLC cabinet, and automation equipment that stays within those limits. The DIN rail format also suits panel-based installations.

Is the MDR-60-48 suitable for building automation panels that use 48VDC devices?

It can be used in building automation and control cabinets where the system requires 48VDC and the load is no more than 1.25A or 60W. The 85-264VAC input supports a broad AC input range for panel power conversion. Its 40 mm wide housing helps when enclosure space is constrained.

Can this power supply be used for 48V industrial communication or control equipment on DIN rail?

Yes, it is appropriate for 48V industrial communication or control equipment when the total demand remains within 60W and 1.25A. The single-output DIN rail design is intended for orderly mounting inside automation cabinets. The compact 100.0 × 90.0 × 40.0 mm size is useful in dense control layouts.

Is the MDR-60-48 a good choice when I need a slim 48V power supply in a crowded enclosure?

Yes, this unit combines a 48V output with a compact DIN rail housing that measures 100.0 × 90.0 × 40.0 mm. That makes it practical for tight control cabinets where space planning matters. It still provides up to 1.25A and 60W in that compact form.

Should the MDR-60-48 be used inside a control cabinet or in exposed environments?

This model is best suited to installation inside a control cabinet or protective enclosure because no exposed-use IP rating is listed in the provided specs. Its operating temperature range is -20°C to +70°C, with output derating at higher temperatures per the derating curve, which supports enclosed industrial conditions. For direct outdoor exposure, buyers usually need a supply with a stated environmental protection rating.

What are the main differences between the MDR-60-48 and other MDR series options?

Within the MDR-60 series, the MDR-60-48 provides 60W at 48V and 1.25A. The other models on the same sheet are the MDR-60-5 at 50W, 5V, 10A; the MDR-60-12 at 60W, 12V, 5A; and the MDR-60-24 at 60W, 24V, 2.5A.
