Overview
The OEC UroView® 2800 Generator is part of a family of compact high frequency X-Ray generators. The various generators
operate on the following voltage and wattage ranges:
Three Phase
480 VAC
80 kW 65 kW
Three Phase
400 VAC
80 kW 65 kW
Single Phase
208 VAC
40 kW
The generators are capable of handling 1msec to continuous exposures ranging from
1 mA up to 600 mA, with constant potential independent of line voltage variations. Power generation is by a high-frequency
converter (High voltage ripple: 40KHz-140KHz) with low kV and mA ripple, excellent accuracy and dose reproducibility.
The generators also include a thermal load interactive integrator ensuring optimum use of the heat protection curve of the x-ray
tube and feature efficient installation (no generator calibration), and application error codes to ensure fast troubleshooting.
The generator is composed of a high voltage chain including the kV Control PCB, power inverter and HV Tank, Anode Rotation
PCB, Tube Filaments Heater PCB, and a control bus for communication between the functions. A DC bus is utilized for power
distribution to each function, input voltage for DC conversion, an AC/DC function, a low voltage power supply, and application
software, running on the kV Control PCB.
The above high voltage chain components are located in four chassis box compartments of the generator chassis. The Rotation
Module contains the Rotation PCB, while the LVPS-400 module contains the Low Voltage Power Supply and the large and small
Heater Filament PCBs. (Refer to the Generator Assembly Diagram on the following page.)
The AC/DC Module contains the EMC Filters, the AC/DC Power Supply and the Capacitor and Rectifier assembly.
