PVB3-D24-D15-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI Inc recommends a PCB layout with a large copper area underneath the module to dissipate heat effectively. A minimum of 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a thermal pad.
• How do I ensure reliable soldering of the module?
  To ensure reliable soldering, CUI Inc recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 217°C to 220°C. The module should be soldered within 3 seconds to 5 seconds, and the solder joints should be inspected for any signs of cold soldering or bridging.
• What is the maximum allowable voltage derating for this module?
  CUI Inc recommends derating the input voltage by 10% to 15% to ensure reliable operation and to prevent overheating. This means that if the module is rated for 24V input, the maximum allowable voltage should be derated to 21.6V to 22.8V.
• How do I troubleshoot issues with the module's output voltage?
  To troubleshoot issues with the output voltage, CUI Inc recommends checking the input voltage, output load, and ambient temperature. Ensure that the input voltage is within the specified range, the output load is within the recommended range, and the ambient temperature is within the specified operating range. Also, check for any signs of overheating, such as excessive temperature rise or burning smell.
• What is the recommended input capacitor value and type for this module?
  CUI Inc recommends using a high-quality, low-ESR input capacitor with a value of 10uF to 22uF, and a voltage rating of 25V to 35V. The capacitor should be placed as close to the module's input pins as possible to minimize noise and ripple.
