The XR1000 series is a component power supply for industrial x-ray systems, elemental analysis equipment,
x-ray diffraction spectrometers, and materials process monitoring applications. It incorporates a floating filament supply that is automatically controlled by the integral beam loop. It is based on the proven HiTek Power IGBT converter, ensuring high efficiency and reliable operation. The XR1000 units are available with either an analog or RS-232 control interface.

Specification range Specifications apply above 5% of rated output voltage and current
Ripple < 0.25% of setting plus 0.25% of rating, peak to peak
Arc Count and Extinguish
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.
Metering Provided as part of an alphanumeric display; Voltages are displayed with a resolution better than 0.5% of rated output. Current is displayed with a resolution of better than 1.5% of rated output
Status indication The alphanumeric display shows the status of the interlock and the reason for any trip condition.
Voltage regulation
Line < 0.05% change in output voltage for a 10% change in line voltage
Static load < 0.05% change in output voltage for a 5 to 100% change in output current
Dynamic load < 5% change in output voltage for a 5 to 100% change in output current, recovery to within 1% of previous setting within 200 msec
Beam current regulation
Line < 0.05% change in output current for a 10% change in line voltage
Load < 0.05% change in output current for a 60% change in rated output voltage
