  • Publication number: 20050231178
    Abstract: X-Ray equipment, that as well as having a controlled current converter, a capacitor bank, an inverter, a supply source, and a high voltage transformer, has inlet voltage evaluation equipment that activates relays of the connection points of an auxiliary supply transformer so that it is not necessary to manually carry out any change in the supply connections depending on the supply voltage. Furthermore it is possible to carry out the charging of the capacitors in a programmed manner, and the charging voltage of the capacitor bank is fixed and independent of the supply voltage, the equipment being able to operate automatically at a voltage between 90 and 264 volts.
