Tools of the Trade: Vaunix Four-Port Lab Brick® USB Hub

Specially designed for USB super users, such as video and audio techs, the four-port Lab Brick® USB Hub (model LPH-204B) offers the highest power in the industry, according to Vaunix, and delivers it to all ports simultaneously and continuously. The self-powered, industrial quality hub features an oversized power supply capable of providing as much as 1A at +5 VDC to each of its four USB ports simultaneously. It also includes a charge while sleep mode, so it continues delivering power in the absence of a host PC or if the host PC goes to sleep. The L hub supports low speed, full speed, and high speed peripherals with data transfer rates to 480 Mb/s with Vbus regulation of +/- 2% typical over all specified load conditions. It provides digital voltmeter (DVM) probe access in order to monitor device load current on port one, and offers over-current protection on all four ports. The hub operates from +12-VDC, is designed for operating temperatures from -30°C to +55°C, and exceeds USB 2.0 and 1.1 standards. Accessories include mounting provisions for installation into various locations, such as test benches, test racks, desks, and vehicles. A 12-V, 24-W AC/DC adapter and USB host cable are also provided.
