VFB600-D48-S28 Frequently Asked Questions (FAQ)

  • CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of 1-2 W/m-K should be used 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 VFB600-D48-S28 is 220uF. Exceeding this value may cause instability or oscillation in the output voltage.

  • While the VFB600-D48-S28 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 5-10A, depending on the specific application and input voltage. The fuse should be sized to protect the module from overcurrent conditions.
