XRV320 and XRV350 Overview:
XRV320 and XRV350 (Rear Panels)
The 320kV and 350kV XRV Generators are
specifically designed to operate 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
320kV system has a maximum voltage of 160kV. One is
positive 160kV with respect to ground while the other is
negative 160kV with respect to ground. Likewise, the
350kV model has a maximum of 175kV each with
respect to ground. Each generator measures 7.16” W x
10.09” x H 24” D (excluding handles). The rear of the
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-24 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 320 or XRV350 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 XRV320 and XRV350 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
