PDQ30-Q48-S5-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use this module in a high-vibration environment?
  Yes, the PDQ30-Q48-S5-D is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in high-vibration environments. However, it's essential to ensure proper mounting and screw torque to prevent damage.
• What is the maximum cable length for the input and output connectors?
  CUI recommends keeping the input and output cable lengths as short as possible to minimize voltage drops and electromagnetic interference (EMI). However, the maximum recommended cable length is 12 inches for the input and 6 inches for the output.
• Is the module protected against overvoltage and undervoltage conditions?
  Yes, the PDQ30-Q48-S5-D has built-in overvoltage protection (OVP) and undervoltage protection (UVP) circuits to prevent damage from input voltage faults. The OVP threshold is 52V, and the UVP threshold is 36V.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PDQ30-Q48-S5-D can be used in redundant or parallel configurations to achieve higher power output or redundancy. However, it's essential to ensure proper synchronization and control of the modules to prevent damage or instability.
