VBM-70-12-H Frequently Asked Questions (FAQs)

  • CUI recommends a PCB layout with a minimum of 2 oz copper thickness, a 1-inch square copper pad under the module, and multiple vias to dissipate heat effectively.
  • To ensure reliable startup and shutdown, CUI recommends a soft-start circuit to limit inrush current, and a shutdown circuit that slowly discharges the output capacitors to prevent voltage spikes.
  • The maximum allowable capacitance on the output of the VBM-70-12-H is 2200 μF. Exceeding this value may cause instability or oscillation in the module.
  • Yes, the VBM-70-12-H is designed to withstand high-vibration environments. However, CUI recommends following the recommended PCB layout and securing the module with screws or adhesive to ensure reliable operation.
  • CUI recommends following a systematic troubleshooting approach, starting with visual inspection, then checking input voltage, output voltage, and current. Consult the datasheet and application notes for specific guidance.
