The XR2000 series incorporates a switching floating filament supply, allowing use of both large and small focus filament connections within an x-ray tube. The filament supply is automatically controlled by the integral beam loop. This series provides an RS-232 control interface and is based on the proven HiTek Power® IGBT converter, ensuring high efficiency and reliable operation.

Arc count and extinguish
ACE Each time the ACE system detects an arc, it blanks the supply off for a brief period to extinguish the arc. The unit is then allowed to recover. If more arcs occur, they are counted to determine the arc rate; if this exceeds a safe level, the power supply is shut down. The parameters are factory set.
