USB Hubs Voltage General Information

Last Updated: Apr 22, 2014 02:21PM COT

This article applies for USB hubs: KUH-590, KHC-345, KUH-190, KNS-110B.


​Some of our USB devices comes with a AC Power jack input that applies in case that the USB port on your PC can't give enough voltage to the USB device, a common error message would appear: "USB device not recognized".  If this is your case, you can use a 5V AC adapter

The Current for each device and polarity of the AC Adapter needs to be as follows:

KUH-590: 2A

KHC-345: 1.5A

KUH-190: 0.5A

KNS-110B: 2A
