100W X-Ray Generator

La serie uXHP es el resultado de las técnicas de fabricación excepcionales de empaquetado de alto voltaje y montaje superficial de Spellman en conjunto con su tecnología de encapsulamiento de diseño propio, lo cual produce el diseño ultra compacto de este módulo generador de rayos X. La serie uXHP energiza tubos de rayos X con cátodo aterrizado de distintos fabricantes reconocidos, con capacidad de salida de alto voltaje de 50 kV, 65 kV, 80 kV a 5 mA, limitada a 100 W. La uXHP utiliza un circuito de control de filamento de lazo cerrado para proporcionar una corriente de haz altamente regulada. La fuente del filamento de CD de bajo ruido opera entre 0.3 A y 3.5 A. Ofreciendo una regulación precisa, altamente estable y de bajo rizo, la uXHP proporciona a los usuarios el control analógico local y remoto para ajustar el voltaje del haz, la corriente de emisión y el límite de la corriente del filamento. Las interfaces USB, Ethernet y RS-232 son estándar.

Interlock Configuration

Digital Interface

The uXHP features a standard USB, RS-232 and Ethernet digital interface. Utilizing these standard digital interfaces can dramatically simplify power supply interfacing requirements saving the user both time and money, while enhancing functionality and overall capabiity. Spellman provides a GUI with the uXHP that allows the customer to both customize operational features of the uXHP while also providing basic power supply operational features. Details of the uXHP’s digital interface capability are described in detail in the uXHP manual.

Varian VF-80J X-Ray Tube

The uXHP was specifically designed in cooperation with Varian to power their new VF-80J X-Ray tube. This joint effort resulted in the creation of both the VF-80J X-Ray tube and the uXHP X-Ray generator. The Varian VF-80J tube is uniquely rated to run at up to 80kV @ 100 watts, 4mA maximum. The uXHP was explicitly designed to operate at up to 80kV and provide 100 watts down to 25kV, so customers could make full use of the capabilities of the VF-80J X-Ray tube. Varian and Spellman, working together to push the boundaries of X-Ray technology.
