MDS20A-12 datasheet by Mean Well

MDS20A-12 Frequently Asked Questions (FAQs)

• What is the maximum ambient temperature for the MDS20A-12?
  The maximum ambient temperature for the MDS20A-12 is 70°C, but it can be derated to 50°C for high reliability applications.
• Can I use the MDS20A-12 in a humid environment?
  Yes, the MDS20A-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 MDS20A-12?
  The MDS20A-12 has a minimum load requirement of 10% of the maximum output current to maintain stability and regulation.
• Can I parallel multiple MDS20A-12 modules to increase the output power?
  Yes, you can parallel multiple MDS20A-12 modules, but you need to ensure that the output voltage and current are matched, and the modules are connected in a way that prevents current imbalance.
• What is the MTBF (Mean Time Between Failures) of the MDS20A-12?
  The MTBF of the MDS20A-12 is approximately 550,000 hours at 25°C, calculated according to MIL-HDBK-217F.
