DC/DC power supply XR250

regulatedfor X-ray sources

Genvolt have designed and manufactured a large variety of power supplies to meet a multitude of requirements. These power supplies were designed specifically for individual customers and whilst they are not available as 'off the shelf' products we are able to use these designs and others to create a tailor-made solution to your high voltage requirements. The Genvolt XR250 illustrates Genvolt’s capability to produce innovative designs in response to challenging specifications. Genvolt has a stock of design techniques and approaches for solving unusual problems presented by customers. The model shown here is designed to operate from a 24- to 48VDC supply, in the harsh environment of a steel strip rolling mill where it is positioned between the rollers. Because this is a very hot environment, water-cooling is mandated. This flows through a labyrinth of holes around the electronics and the HV areas. The source is connected directly to an X-ray tube and it is the intensity of the X-rays passing through the steel which is used as the feedback parameter for controlling the pressure on the rollers and thus the thickness of the metal strip produced. This calls for a highly stable HV source, both in terms of the voltage applied to the cathode of the tube and also the anode current. The latter is regulated in a closed-loop manner by the HV supply to a high degree of stability and repeatability.
