Test conditions and notes6
- 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
- 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
- 3.Line regulation is measured from low line to high line at rated load.
- 4.Load regulation is measured from 10% to 100% rated load.
- 5.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
- 6.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ
Can I use the MDS02N-05 to step a 24V-class supply down to 5V for embedded control electronics?
Yes, this model is intended for unregulated conversion from 21.6~26.4V input to 5V output. Its 2W rating makes it suitable for low-power embedded controllers, interface boards, or monitoring electronics rather than larger 5V devices.
Is the MDS02N-05 a fit for industrial automation panels that distribute 24V but need a local 5V rail?
It can fit that role when the upstream supply falls within the 21.6~26.4V range. The 2W output and compact 19.5 × 9.8 × 12.5 mm form factor are aligned with small local power rails inside automation electronics.
Can this converter power low-power communications or logic sections from a nominal 24V DC system?
Yes, the product is designed to produce an unregulated 5V output from a 24V-class input range of 21.6~26.4V. With a 2W power rating, it is best used for low-power logic, communications, or supervisory circuitry.
How suitable is the MDS02N-05 for outdoor or temperature-extreme equipment?
The operating temperature is specified from -40°C to +85°C, which supports broad industrial temperature exposure. No IP rating is listed in the provided specs, so the unit is not described here as a standalone outdoor-rated enclosure product.
How does the MDS02N-05 compare with the rest of the MDS02N family?
The MDS02N range includes 5V, 12V, and 15V single outputs, all at 2W with 21.6~26.4V input. Besides this 5V, 40~400mA model, the siblings are MDS02N-12 at 12V and 17~167mA and MDS02N-15 at 15V and 13~133mA.
