StarTech.com 7-Port USB 3.0 Hub - 5Gbps - Metal Industrial USB-A Hub with ESD Protection & 350W Surge Protection - Din Rail Wall or Desk Mountable - TAA Compliant USB Expander Hub (ST7300USBME)

We have these on our telescope, and they have worked quite well. Of course we power them externally.After 3 years, of constant use in all weather, one broke. I am not sure why, but we just replaced it.

You need to take it apart and swap jumpers (see direction) in order to utilize an external power supply. Works perfectly at full utilization.

I recommend this item if you need a real industrial grade performance.This item comes without a power adapter, which makes the perfect sense to me.For general purpose it works without a power adapter as usual passive USB HUB.To take advantage of the surge protection of this item you need to power it up.As described in the technical details you may use DC power supply from 7V to 48V, which obviously makes a difference in the cost, so the customer can choose the right one.I specifically needed an industrial grade of performance, as previously I had about a dozen of USB HUBs, but even a best one of them still "kicks out" some connected devices when I connect a Dual-Dock with 2 14GB disks in it.I bought power supply (DC 48 V, 3.5 V, 120 W). Following instructions - it took 20 minutes to connect power to this item. I am using this item for the first day, very intensively. So far - even under the extreme conditions, utilizing all 7 ports, including the Dual-Dock with 2 x 3.5" disks - no "kick outs".I bought another (4-port) StarTech.com 4-Port USB 3.0 Hub - for my other PC. Both HUBs work at industrial grade performance.

I have a test bench that uses a *lot* of USB based test equipment, and even with ESD mats and sprays, I always seemed to damage my USB 3 hubs with static discharges, or iffy units under test. I have used the StarTech USB 2.0 hardened hubs for years, and have yet to have a single failure. So, I added in one of their USB 3 units to the mix. It has worked flawlessly and the ability to run from just about any voltage source is a big plus.

Good value and just what I needed for all my ports. Looks like industrial grade.

Definitely the way to go if you are looking for a USB hub. Purchased multiple times and have had no issues with these units.

Stopped operating using it for a 2nd time. Nothing connects thru it.

It is really nice to have a metal-encased USB3 hub that accepts a wide range of voltages for powering USB devices! It is an excellent match for a West Mountain Radio RigRunner, and I pull power for the hub from the RigRunner, and power the whole thing from a 13.8 power supply. Keeping everything on one power supply keeps connections and portability easy.
