When paired with the HUB7i optically isolated 7-port USB hub, the TR129 is a medical grade power supply providing 4000 VAC isolation to the host computer. This protects the computer from voltage spikes, power surges, and ground loops that are commonly found in industrial environments, and offers the highest level of protection in the industry.

The TR129 is a switching power supply with a universal input from 100-240VAC and a rated output of 5VDC at 4 amps, supplying a full 20 watts of power to connected devices via the 2.1mm barrel plug. An integrated cable strain relief prevents damage to the 72 output cord.
