PBO-15C-24 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended. Additionally, ensure good airflow around the module and consider adding a heat sink if operating in high-temperature environments.
• How do I ensure electromagnetic compatibility (EMC) with other components in my system?
  CUI's PBO-15C-24 is designed to meet CISPR 22 Class B emissions standards. To ensure EMC, follow proper PCB layout and grounding practices, use shielding if necessary, and consider adding EMI filters or common-mode chokes to your design.
• What is the maximum allowable capacitance for the output filter capacitor?
  CUI recommends an output filter capacitor with a maximum capacitance of 10uF to ensure stability and prevent oscillations. Exceeding this value may lead to instability or reduced performance.
• Can I use the PBO-15C-24 in a redundant or parallel configuration?
  Yes, the PBO-15C-24 can be used in redundant or parallel configurations to achieve higher power ratings or improve reliability. However, ensure proper synchronization and ORing diodes are used to prevent back-feeding and damage to the modules.
• What is the recommended input fuse rating and type for overcurrent protection?
  CUI recommends a fuse rating of 5A to 10A, depending on the specific application and input voltage. A slow-blow fuse (e.g., Littlefuse 5A or 10A) is recommended to allow for inrush currents during startup.
