When it comes to needing a power supply, this feature is your best friend. Or your superhero. Maybe even your saving grace. Whatever your state of frustration at manually setting up multiple hubs and power supplies for validation, you need the Vbus Validation feature for 2 reasons:

The Vbus Validation feature gives you complete power sourcing control ​​through its “Power Supply” mode. It lets you set a specific voltage and current limits just like a programmable power supply–turning your USBExt3c into a 2 port programmable power supply.
This feature on its own is a game-changer. You can allocate significantly more time to product testing and validation when your power supply is integrated into your analysis/test hub.

2. You can also override the hub’s sourcing set point, changing the output voltage beyond the negotiated range of PD or QC. See what happens outside of “normal” power circumstances by overloading a device. Battery swell? Malfunction? Or give it less power and see what communications take place behind the scenes.

The per-port control and ability to truly test peripherals make Vbus Validation an essential part of the USBExt3c. Get the most out of your equipment (and your time) by using the most sophisticated industrial USB Hubs.
