HiTek Power announces X-ray power supply for industrial and scientific analytical applications

The XRF50 provides up to 50kV for the X-ray tube anode with a maximum current of 1.0mA. It also provides a low voltage output for the X-ray tube filament, with a current of up to 1.0A and a maximum voltage of 14V (Power limited to 3W), referenced to the 50kV negative output voltage. A floating grid output is also incorporated, providing an output voltage of 0 to+150V DC at up to 20mA and 0 to -200VDC at up to 100microamps referenced to the 50kV negative output voltage.

The new unit has been designed to offer the high stability and low ripple demanded by today’s applications. Ripple on the high voltage output is less than 0.05 per cent of set voltage +15V peak-to-peak with a maximum of 25V p-p. Static load regulation for voltage is less than 0.01 per cent ±1V from 0.2mA to full load. Temperature drift is ±0.1 per cent over an 8 hour period after 30 minutes warm-up.

The RS232 interface provides the high levels of remote control and monitoring needed to meet the requirements of modern X-ray systems to be controlled more finely and the growing need to protect ever-more-expensive tubes. Flashover and continuous short-circuit protection are also incorporated, plus trips for over-temperature, output over-voltage and arc.
