XRV450 Overview :
XRV450 (Rear Panels)
The 450kV Generator is specifically designed to operate with
bipolar x-ray tubes. The X-ray tube requires a negative kV
generator (cathode) which includes a filament supply and a
positive kV output (anode) generator. Each generator on the
450kV system has a maximum voltage of 225kV. One is
positive 225kV with respect to ground while the other is
negative 225kV with respect to ground. Each generator
measures 17” W x 18.90” (including castors) x H 30.72” D
(excluding cable well). The rear of each chassis has all of the
necessary connectors for power input, controls, monitoring,
and kV output. Each connector on the rear panel is clearly marked for installation purposes. An
interconnect cable on the cathode side supplies auxiliary power to the anode generator. Two additional
25 pin DB style cables interface the anode generator feedback and inverter signals to the main control
board residing in the cathode generator supply. The mains input on the cathode generator includes an
Amphenol style mating connector and an additional DB-25 pin connector for the user I/O analog control.
Both the cathode and anode kV outputs mate with a standard R-28 type connector. These are available
from Spellman High Voltage Corp. in different lengths and configurations for installation of the X-ray
tube. Standard Graphical User Interface (GUI) software is included with the XRV 450 Generator. A
personal PC is required for installation. The user has the option of connection to a USB, Ethernet or Com
Port. The control and monitoring of the XRV450 also includes an analog I/O connector for custom
configurations. An additional optional touch screen controller (XRVC) is also available from Spellman
High Voltage Corp..
