X-ray Source Electronics Set XREC20

XREC20 electronics set dedicated for controlling SAX X-ray sources.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.


The XREC20 set comprises 2 units for full control of the SAX X-ray Sources: XREC20-I emission controller and XRHV02-PS high voltage power supply.

The XREC20-I unit controls the emission current of the X-ray source and also the XRHV02-PS high voltage power supply, displaying both the high voltage and emission current on a single display. Unit allows measurement of working time and anode power. The X-ray source electronics set has both operational and standby modes, guaranteeing the most accurate and stable emission at the start of an experiment. Easy firmware update via USB port (XREC20-I). Unit can be remotely controlled via RS232/485 or Ethernet interfaces. Autosave function (XREC20-I unit) for saving your parameters/unit pre-set and applying them automatically after restart.
