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-100-48 to power 48V devices in an industrial control panel?

Yes, this model is suited to industrial control panels that need a 48V DC supply up to 2A. Its 96W output and DIN rail form factor make it appropriate for centralized 48V power distribution inside automation cabinets.

Is the MDR-100-48 suitable for PLC and industrial automation cabinets that use 48V DC?

It can be a fit where the PLC cabinet or automation assembly requires 48V DC and the connected load stays within 2A. The 55 mm wide DIN rail housing also helps when panel space is limited.

Can this 48V DIN rail power supply be used for building management and control enclosures?

Yes, it is appropriate for building management or control enclosure applications that use 48V DC equipment and need up to 96W. The wide 85-264VAC input is useful where panel power standards vary across sites.

How does the MDR-100-48 compare with other MDR series models?

Within the MDR-100 series, the MDR-100-48 provides 96W at 48V and 2A with 87% typical efficiency, the MDR-100-24 provides 96W at 24V and 4A (86%), and the MDR-100-12 provides 90W at 12V and 7.5A (83%). All three share the 55 x 90 x 100 mm DIN rail housing and 85 ~ 264VAC input.

Is the MDR-100-48 intended for open-air use or for control cabinets?

This DIN rail power supply is best suited to protected indoor control cabinets and enclosures rather than exposed open-air locations. Its operating temperature range is -10°C to +60°C, so the enclosure environment should stay within that range.
