PQA30-D24-S24-D Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • The maximum allowable output capacitance for the PQA30-D24-S24-D is 220uF. Exceeding this value may cause instability or oscillation in the output voltage.
  • While the PQA30-D24-S24-D is designed to meet standard industrial vibration and shock requirements, CUI recommends additional mechanical support and securing the module to the PCB or chassis to ensure reliable operation in high-vibration or high-shock environments.
  • CUI recommends a fuse rating of 5A or less to protect the module from input overcurrent conditions. The fuse should be located as close to the input terminals as possible to minimize voltage drop and ensure effective protection.
