  • Alimentación de filamento flotante integrada
  • Control de emisión local y remoto
  • Opción de interfaz digital

GENERADORES DE RAYOS X INDUSTRIALES DE 50 W-75 W

La serie MFX 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 para aplicaciones de OEM.

La serie MFX está diseñada para energizar tubos de rayos X de filamento flotante de distintos fabricantes. Está equipada con salida de alto voltaje de 0 kV a 50 kV (o 0 kV a 65 kV) y hasta 2 mA de corriente de emisión limitada a 50 W, 65 W o 75 W y operando con +24 VCD de entrada. La MFX utiliza un circuito de control de filamento de lazo cerrado para proporcionar una corriente de haz altamente regulada. La alimentación del filamento de CA flotante opera entre 0.3 A y 4 A. Ofreciendo una regulación precisa, altamente estable y de bajo rizo, la MFX 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. Opcionalmente, están disponibles las interfaces RS-232 y Ethernet.
