MDS15B-12 datasheet by Mean Well

MDS15B-12 Frequently Asked Questions (FAQs)

• What is the maximum ambient temperature for the MDS15B-12?
  The maximum ambient temperature for the MDS15B-12 is 70°C, but it can be derated to 50°C for full load operation.
• Can I use the MDS15B-12 in a humid environment?
  Yes, the MDS15B-12 has a conformal coating that protects it from humidity, but it's still recommended to follow the derating curve for high humidity environments.
• What is the minimum load requirement for the MDS15B-12?
  The MDS15B-12 requires a minimum load of 10% to maintain stability and regulation, but it's recommended to operate at 20% or higher for optimal performance.
• Can I parallel multiple MDS15B-12 units for higher power?
  Yes, you can parallel multiple MDS15B-12 units, but you'll need to ensure that the output voltage is matched and the units are synchronized to prevent oscillation.
• What is the MTBF (Mean Time Between Failures) for the MDS15B-12?
  The MTBF for the MDS15B-12 is approximately 550,000 hours at 25°C, calculated according to MIL-HDBK-217F.
