SE-450-3.3 datasheet by Mean Well

SE-450-3.3 Frequently Asked Questions (FAQs)

• What is the maximum ambient temperature for the SE-450-3.3?
  The maximum ambient temperature for the SE-450-3.3 is 50°C, but it can be derated to 40°C for full load operation.
• Can I use the SE-450-3.3 in a high-humidity environment?
  Yes, the SE-450-3.3 is designed to operate in humid environments, but it's recommended to keep the relative humidity below 90% to prevent condensation.
• What is the hold-up time for the SE-450-3.3?
  The hold-up time for the SE-450-3.3 is approximately 16ms, which means the output voltage will remain stable for at least 16ms in the event of an input power failure.
• Can I parallel multiple SE-450-3.3 units to increase the output power?
  No, the SE-450-3.3 is not designed for parallel operation. If you need higher output power, consider using a higher-power model from Mean Well or a different manufacturer.
• What is the MTBF (Mean Time Between Failures) for the SE-450-3.3?
  The MTBF for the SE-450-3.3 is approximately 550,000 hours, which is calculated based on MIL-HDBK-217F standards.
