Title: (EN) Discharge module for X-ray cable
Abstract: front page image
(EN)

A discharge module positionable between a high-voltage power supply and an X-ray tube for discharging any capacitive voltage remaining on the cable connecting the same. The discharge module includes a low-voltage control portion which is optically coupled to a high-voltage portion that includes a switch for activating a discharging resistor series. The module also monitors the current through the X-ray tube to initiate a fault if the current exceeds a predetermined maximum.
