VOF-S12B-12 Frequently Asked Questions (FAQs)

  • 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 operating temperature below 100°C.
  • The VOF-S12B-12 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.
  • 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 affect the overall performance.
  • Yes, the VOF-S12B-12 can be used in a redundant or N+1 configuration, but it requires additional external circuitry and control logic to ensure seamless switchover and proper operation.
  • CUI provides an MTBF rating of 1.5 million hours at 40°C, calculated according to MIL-HDBK-217F. However, actual MTBF may vary depending on the application, operating conditions, and quality of the PCB assembly.
