2. Instruction for use:
Scope of application :
(1) Contain strong electricity and strong interference work environment
part electric circuit contain strong electricity and strong interference( such as high voltage, frequency converter, motor drive etc.) environment,When it related to connecting a computer occasion,must isolate to ensure computer and personal safety.
(2)Noise sensitive area
Computer is a large noise source, In the field of noise sensitivity that we can through this device to USB interface make communication isolate, such as high-precision USB data acquisition system, HIFI sound system.
(3)USB debugging equipment
like all kind of USB interface JTAG/SWD Emulator、ISP/ASP/IAP/ICP Downloader etc. When you at the process of debugging, often can't connect, simulation is abnormal ,can use Usb isolator try to improve this situation.
(4) all kinds of industrial control USB devices
in the industrial environment,USB device Frequent crashes,like USB Mouse, keyboard, USB to serial port and other communication devices,USB isolators can reduce the chance of crashes and damage to these devices in industrial environments,sometimes we need lengthen USB line,USB isolator can Acting as a very good USB repeater, also can isolation upstream and downstream equipment in ground pressure difference.
(5)Other common USB peripherals such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.
the most important and primary consideration is Human safety,but some medical equipment through USB interface with computer connect, In the process of collecting data or treatment on the human body,need to have direct electrical contact with the human body.
To avoid cause electric shock by the high voltage that may be transmitted from the computer to the human body through the device and interface lines, the electrical isolation of the interface line becomes one of the important protective measures.
