At just 2.0 x 1.7 x 0.8 inches, these litle isolators pack a powerful punch against
electrical noise, surges and spikes - up to 4kV isolation. Protect expensive PCs
and equipment from damaging electrical storms, power surges and other high
EMI/RFI disturbances. This isolation barrier eliminates ground loops which are
disruptive in measurement applications.
UH401 and UH401SL provide 4 kV isolation.
UH401-2KV and UH401SL-2KV provide 2kV isolation.
All models are USB bus powered and provide up to 100mA of current to attached
downstream devices when they are attached to a full power (500 mA) USB host
port.
These data rates are preconfigured at the factory. You should select a model that
is appropriate for your USB peripheral (low speed or full speed). Note that high
speed (480 Mbps) cannot be isolated with existing technology.
Four models are available. Select a low speed version, UH401SL or UH401SL-
2KV, if you are using a low speed device. Low speed devices are typically human
interface devices such as a mouse or keyboard. Use the full speed version,
UH401 or UH401-2KV for full speed USB devices.
