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 when
used with 3 phase power, 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. 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.
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
