RT-85D datasheet by Mean Well

RT-85D Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the RT-85D?
  The RT-85D can operate in temperatures ranging from -40°C to 85°C, but the maximum operating temperature range for optimal performance is between 0°C to 60°C.
• Can I use the RT-85D in a humid environment?
  Yes, the RT-85D is designed to operate in humid environments, but it's recommended to keep the relative humidity below 90% to prevent condensation and ensure reliable operation.
• What is the maximum input voltage tolerance for the RT-85D?
  The RT-85D can tolerate input voltage fluctuations of up to ±10% of the nominal input voltage without affecting its performance or reliability.
• Can I use the RT-85D in a high-altitude application?
  Yes, the RT-85D is designed to operate up to 5000 meters above sea level, but it's recommended to derate the output power by 1% for every 100 meters above 2000 meters to ensure reliable operation.
• What is the MTBF (Mean Time Between Failures) rating for the RT-85D?
  The MTBF rating for the RT-85D is approximately 550,000 hours at 25°C, calculated according to MIL-HDBK-217F.
