PDQE10-Q48-S24-D 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, a thermal interface material (TIM) can be used to improve heat transfer between the module and the heat sink.
• How do I ensure reliable start-up and shutdown of the power module?
  To ensure reliable start-up and shutdown, CUI recommends a soft-start circuit to limit inrush current and a shutdown circuit to prevent voltage spikes. Additionally, a minimum input capacitance of 10uF is recommended to ensure stable operation.
• What is the maximum allowable output capacitance for this module?
  The maximum allowable output capacitance for the PDQE10-Q48-S24-D is 220uF. Exceeding this value may cause instability or oscillation in the output voltage.
• Can I use this module in a high-vibration or high-shock environment?
  While the PDQE10-Q48-S24-D is designed to meet standard industrial vibration and shock requirements, CUI recommends additional mechanical support and fixation for high-vibration or high-shock environments to ensure reliable operation.
• How do I monitor and control the module's temperature?
  The PDQE10-Q48-S24-D has a built-in temperature monitoring pin (VTM) that can be connected to a temperature monitoring circuit or a microcontroller. CUI recommends monitoring the temperature to ensure operation within the specified range (–40°C to +85°C).
