Supplies go easy on costly X-ray tubes

HiTek Power has introduced the HiGen 2000 series of 2kW X-ray generator power supplies

The new units produce the tightly controlled power needed to drive and control X-ray tubes, and incorporate high levels of remote control and monitoring to meet the needs of modern X-ray systems to be controlled more finely and the growing need to protect ever-more-expensive tubes. The HiGen 2000 supplies have been designed for use as component power supplies in industrial and analytical X-ray systems and low-energy industrial radiography applications.

They offer output voltages of up to 60 or 90kV coupled with high stability and low ripple.

The units' IGBT convertor design makers them very robust.

Tube arc suppression and interlocks are provided as standard.

Filament current and voltage are sensed at the output terminals of the high-voltage connector.

This allows the filament current limit to be set very close to the maximum operating current of the tube, as current sense is far more accurate than the traditional primary side sensing.

This affords better protection of the X-ray tube's filament but permits maximum use of its capabilities.

The supplies use microcontrollers to provide a versatile subsystem.

nonvolatile memory within the microcontroller is used to store critical tube parameters, which can be called up via the RS232 interface.

Parameters such as maximum beam current, maximum filament current, maximum voltage and maximum power can be stored for each tube that a customer wishes to use.

This ensures that the generator never exceeds the maximum parameters of the tube.

There is also a facility to log how long the generator has been running, the maximum ambient temperature, and the maximum temperature of critical components within the generator.

A digital bus system is used for internal communications, which means that the generator is easily upgradeable to suit specific customer requirements without the need for hardware changes.
