SP-75-15 datasheet by Mean Well

SP-75-15 Frequently Asked Questions (FAQs)

• What is the maximum ambient temperature for the SP-75-15?
  The maximum ambient temperature for the SP-75-15 is 50°C, but it can be derated to 40°C for full load operation.
• Can the SP-75-15 be used in a redundant configuration?
  Yes, the SP-75-15 can be used in a redundant configuration, but it requires an external ORing diode and a redundant controller to ensure proper operation.
• What is the hold-up time for the SP-75-15?
  The hold-up time for the SP-75-15 is approximately 16ms at full load, which means the output voltage will remain within regulation for at least 16ms in the event of an input power failure.
• Can the SP-75-15 be used in a high-altitude environment?
  Yes, the SP-75-15 can be used in high-altitude environments, but it may require derating to ensure reliable operation. Consult the manufacturer's guidelines for high-altitude operation.
• What is the MTBF (Mean Time Between Failures) for the SP-75-15?
  The MTBF for the SP-75-15 is approximately 550,000 hours, which is calculated based on MIL-HDBK-217F standards.
