VRack Power Distribution Overview
The VRack Power Distribution panel offers worldwide use capabilities as well as multiple AC operations when used with 120VAC input. This power distribution system allows 120VAC input to 120VAC output, 120VAC input to 208VAC output, 220VAC 240VAC input to 220VAC 240VAC output. It also features a 32A per circuit, 3-pole, single-throw breaker as well as an LCD readout that indicates AC Voltage. Also, built-in +5V and +12V outputs power the VRack's built-in network switch and rear rack lighting features. Combine this worldwide capable power distro with the I-Tech HD's Universal, Power-Factor-Corrected Power Supply and the VRack can be used anywhere in the world without the need to re-configure anything in the rack.
Hubbell L21-30 U. S. Operation
Hubbell L21-30 12 120VAC Operation Switch position "Input Twistlock, Output US/120" provides the user with 120V operation to the I-Tech HD amplifiers in the rack. From an external power distribution system, send 3 phase 120VAC power to the X, Y, and Z pin of the Hubbell connector and the VRack will operate in 120V mode. Each I-Tech HD amplifier will see a dedicated X, Y, or Z phase to the line input, neutral, and Ground connection. Amp 1 = X, Neutral, and GND Amp 2 = Y, Neutral, and GND Amp 3 = Z, Neutral, and GND
Hubbell L21-30 208VAC Operation Switch Position "Input Twistlock, Output US/208" provides the user with 208VAC operation to the I-Tech HD amplifiers in the rack. From an external power distribution system, send 3 phase 120VAC power to the X, Y, and Z pin of the Hubbell connector and the VRack will operate in 208V mode. Each I-Tech HD amplifier will see a dedicated line-to-line and ground connection resulting in the VRack operating in 208VAC mode. Amp 1 = X, Y, and GND Amp 2 = Y, Z, and GND Amp 3 = X, Z, and GND

Cee-Form U. S. Operation
Cee-Form 120VAC Operation Switch Position "Input Pin/Sleeve, Output US/120 EU/240" provides 120VAC operation from the Cee-Form pin and sleeve connector. From an external power distribution system, send 3 phase 120VAC power to the X, Y, and Z pin of the Cee-Form connector and the VRack will operate in 120VAC operation mode. Each I-Tech HD amplifier will see a dedicated line-to-neutral connection as well as a ground. Once the Cee-Form connector is landed to the VRack, one can link to the next VRack using a Cee-Form jumper cable. ***To link VRacks using this method at 120VAC, the end user must ensure they have proper AC current available.

VDrive is a digital AES3 transport mechanism that combines a standard 10/100MB network connection with AES3 signals. VDrive uses the unused pins of a 10/100MB network to transport AES3 digital audio signals. As indicated in the chart above, one is able to transmit 4 channels of digital audio using a standard CAT5 cable. [. . . ]
