4. USB Isolator 2 kV HS, #33003
Function
The USB-Isolator 2 kV HS #33003 provides galvanic isolation for
USB connections. The isolator is simply inserted into the existing
USB connection and powered by an external power supply.
The isolator of type #33003 isolates Low-, Full- and HighSpeed USB
connection galvanically with an isolation voltage of at least 2,000 V
DC.
The bus speed is detected fully automatically.
Supply voltage
The USB-isolator requires an external power supply for powering
the galvanically isolated circuitry of the isolator in addition to the
bus-powered USB device.
A suitable wall mount adapter is included with the isolator, though
any 5 V DC power supply with a USB output can be used as long
as it provides an output current of at least 1 A and fulfills the
requirements as outlined in the safety instructions.
The supply voltage is supplied to the isolatod side via a USB type-C
socket. An appropriate adapter cable for connecting the power
supply is also included with the Isolator.

NOTE
The USB A plug on the power cable must not be connected to a
second USB port on the USB host or hub which is connected to the
upstream port of the isolator. Such a connection would short-circuit
the galvanic isolation and render it useless. A galvanically isolated
voltage source is therefore mandatory.
