The PHI 14-040 and 22-040 15kV X-ray source high voltage power supplies are starting to have more frequent malfunctions as they approach 30 years of service.  Although most PHI units can still be repaired to the component level, these X-ray high voltage supplies were manufactured as OEM for PHI by Hippotronics and some of the critical parts have become obsolete.

In order to extend the service life of PHI XPS system we are providing a drop in replacement for the PHI 14-040, 22-040 and 20-040 X-ray high voltage power supplies. The RBD 20-042 X-ray source High Voltage power supply is is now available.

This supply will not only work as a drop in replacement for the above mentioned PHI units; it can also serve as a replacement for other manufacturers’ X-ray source systems including SPECS, VG and VSW.
