VOF-15B-S12 - CUI Inc.

VOF-15B-S12 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-15B-S12 handle input voltage transients and spikes?
  The VOF-15B-S12 has built-in input voltage transient protection, but it's still recommended to add external transient voltage suppressors (TVS) to protect against high-energy transients and spikes.
• 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 voltage sense errors and affect regulation.
• Can the VOF-15B-S12 be used in a redundant or N+1 configuration?
  Yes, the VOF-15B-S12 can be used in a redundant or N+1 configuration, but it requires external ORing diodes and control circuitry to ensure proper operation and fault tolerance.
• What is the MTBF (Mean Time Between Failures) of the VOF-15B-S12?
  CUI provides an MTBF of 1.5 million hours at 40°C, calculated according to MIL-HDBK-217F. However, actual MTBF may vary depending on operating conditions and application.
