[USB-204]USB3.0 Isolator HuMANDATA LTD.
[USB-204] USB3.0 Isolator
Dedicated isolator for USB3.0 SuperSpeed
Overview
USB-204 is a USB 3.0 SuperSpeed(5Gbps) compliant isolator which isolates between a USB host and a USB peripheral device with 3000VDC. With USB-204, it can be expected to eliminate ground loops that can cause measurement errors and equipment from surges, common-mode voltage, static discharge, magnetic fields, and radio frequency interference.There is no need to install any drivers. It works with every operating system such as Windows, Linux, Mac OS X.
*USB-204 was discontinued. Please consider USB-03G1 for a replacement.

Features
- USB host connector which is USB3.0 standard Type B female and have to be connected to a PC or other USB host device

- USB 3.0 SuperSpeed (5Gbps) compliant (Low, Full and Hi Speed are not supported)
- OS-Independent (No drivers required)
-
USB-204 is powered through a USB port (Bus-powered) or an AC adapter (Self-powered)
DC-DC converter supply isolated voltage to a USB peripheral device from a USB host if no external power supply is present - 3000VDC bus isolation
- ESD and surge protection
- Housing material: Plastic
- DIN rail and screw mountable (Attachment is required)
- Includes a USB 3.0 cable (1.0m)
- Includes an AC adapter
- Non-use of 6 Restricted substances of RoHS directive
