USB Isolators

Sept. 24, 2010
At just 2.0 x 1.7 x 0.8 inches, these little isolators pack a powerful punch against electrical noises, 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, designed to meet EN60601-1-1 and EN60601-1-2 for medical applications, isolates up to 4kV - strong enough for hospital and medical use.

These isolators are USB bus powered and provide up to 100mA of current to attached downstream devices. LED indicates power supplied via upstream USB port. Comply with the USB 1.1 standard and transfer data at 12Mbps. 1 meter USB type A to type B cable is included. USB cables, up to standard 5 meters, can be used.
