Part Details for VQE50W-Q24-S24 by CUI Inc

CUI recommends a multi-layer PCB 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 discharge the output capacitors. The module should also be powered up and down slowly (typically 10-20 ms) to prevent voltage spikes and stress on the components.

The maximum allowable capacitance on the output is 2200 uF. Exceeding this value may cause instability or oscillation in the module. It's recommended to use a capacitance value that is as close to the recommended value as possible to ensure optimal performance.

Yes, the VQE50W-Q24-S24 is designed to meet the requirements of IEC 60068-2-6 for vibration. However, it's recommended to follow proper mounting and screw torque procedures to ensure the module is securely fastened to the PCB or chassis. Additionally, the module should be subjected to a vibration test according to IEC 60068-2-6 to ensure its reliability in the specific application.

CUI recommends using an oscilloscope to monitor the input and output voltages, as well as the current sense resistor voltage. The module's protection circuits can be triggered by external events such as input voltage surges or output short circuits. Consult the datasheet and application notes for specific troubleshooting guidelines.
