PBO-3-S12 Frequently Asked Questions (FAQs)

  • CUI recommends a PCB layout with a solid ground plane and a thermal pad connected to a heat sink or a thermal via to ensure efficient heat dissipation. A minimum of 1 oz copper thickness is recommended for the PCB.
  • The PBO-3-S12 has built-in input voltage transient protection, which can withstand voltage spikes up to 100 V for 100 ms. However, it's recommended to add external transient voltage suppression devices for harsh environments.
  • CUI provides a derating curve in the datasheet, which indicates that the output power should be reduced by 2.5% per degree Celsius above 50°C to ensure reliable operation.
  • Yes, the PBO-3-S12 can be used in a redundant or parallel configuration, but it's essential to ensure that the units are synchronized and properly connected to avoid oscillations or instability.
  • CUI estimates the MTBF rating for the PBO-3-S12 to be around 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F.
