These little 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. Model UH401 and UH401SL
provide 4 kV Isolation and are UL 60601-1 Recognized, which makes them
appropriate for use with medical equipment. UH401-2KV and UH401SL-2KV
provide 2 kV 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.

Carrier data charges
may apply.

They comply with the USB 1.1 standard and transfer data at either 12
Mbps or 1.5 Mbps. 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).

Four models are available to choose from. 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 device.
