Generador de Rayos-X de 5W
El XMPF es un generador de Rayos-X de 10kV a 5W diseñado para operar un tubo de Rayos-X de filamento flotante a través de un control de filamento de ciclo cerrado en la corriente de emisión de 0 a 500uA. La fuente para filamento flotante opera de 0 a 0.42 amps a 3.5Vac con limite ajustable en filamento de 0 a 0.42 amps.
El programa de alto voltaje y el programa de emisión de corriente contiene capacidad para efectuar ajustes que simplifican las interfaces en este generador de Rayos-X. Como alternativa, una señal provista de 0 a 10Vdc puede utilizarse para controlar remotamente estas dos señales. Una señal de alto voltaje referenciada y otra de emisión de corriente son contenidas en el equipo. Adicionalmente, una señal referenciada en la corriente de filamento también se encuentra disponible. El activar el modo de Alimentación de Alto Voltaje permite controlar la salida de alto voltaje.
