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)

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.

Great product. Can't beat the price.

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.

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

Great quality, no issues with any of the attached usb devices attached. Consistently functioning as described. Would buy again.

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.

I bought this USB 3.0 hub for use with some astrophotography equipment. I have used it in all manner of conditions ranging down to temperatures as low as -15F and the high dew conditions of a Wisconsin summer which had water basically dripping on my equipment. It has handled all these conditions reliably and superbly - no other hub I've tried worked this well. One small flaw - the 12V DC power connection terminal on the hub doesn't hold on tightly enough to the wires; it is a connection where you tighten a screw to hold the wire in place. The wire has a tendency to slip out and periodically needs to be reinserted and screws tightened. Apart from this one flaw, I am really happy with this hub.

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

Tras 2 años en condiciones extremas, con 90% RH y entre -15 y 30C, sigue funcionando perfectamente en un observatorio astronómico.

Works fine. Fast shipping.

Wir haben inzwischen vier dieser Teile eingesetzt, da ich anfangs von der Bauform und 24V Versorgung überzeugt war. Leider trügt das äußere. Nach kurzer Zeit (i.d.R) weniger als einer Woche Betrieb sind bereits zwei davon ausgefallen. Da diese bei einer industriellen Anlage nicht tolerierbar ist, werden wir nun gegen ein anderes Produkt ersetzen und alle zurücksenden. Beim Handling ist eigentlich nichts falsch zu machen, nach dem Neueinschalten haben sie einfach den Dienst verweigert. Bei diesem Preis geht diese Qualität gar nicht.

This is great product for extending the number of ports. You can charge lower powered devices (not ipads etc) unless you provide extra power via the additional socket. I understand that it's really intended for industrial situations and can be mounted on a din rail but doesn't look out of place wall mounted in an office. It's very well made and works well. It comes with a cable to connect to the computer and a plug for the power socket - I've not used that part. Overall 5 star. It is however extremely expensive so you would really want it over anything else.

Arrived with a rattle on the inside of the unit, for an industrial hub, the quality certainly is unexpected.
