VOF-10B-S15 - CUI Inc.

VOF-10B-S15 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
• How does the VOF-10B-S15 handle input voltage transients and spikes?
  The VOF-10B-S15 has built-in input voltage transient protection, but it's recommended to add external protection components such as TVS diodes or varistors to ensure reliable operation in harsh environments.
• What is the maximum cable length for the output voltage sense lines?
  CUI recommends keeping the output voltage sense lines as short as possible, but a maximum length of 10 inches (25 cm) is acceptable. Longer lengths may cause accuracy issues and require additional compensation.
• Can the VOF-10B-S15 be used in a redundant or N+1 configuration?
  Yes, the VOF-10B-S15 can be used in a redundant or N+1 configuration, but it requires additional external circuitry and control logic to manage the redundancy and ensure seamless switchover.
• What is the MTBF (Mean Time Between Failures) of the VOF-10B-S15?
  CUI provides an MTBF rating of 1.5 million hours at 40°C ambient temperature, calculated according to MIL-HDBK-217F. However, actual MTBF may vary depending on the application and operating conditions.
