GENERADORES DE RAYOS X INDUSTRIALES DE 80 W-640 W

La serie de XRF de generadores de rayos X de Spellman permite un intervalo amplio de voltaje de entrada y alimentación desde 80 W, 320 W o 640 W de potencia de salida con hasta 160 kVCD. Estos generadores de rayos X ligeros y de montaje en bastidor alojan un sistema de alto voltaje en miniatura en un diseño sólido encapsulado y libre de aceite. La serie XRF de generadores de rayos X está diseñada con un circuito de entrada con factor de potencia corregido el cual reduce las emisiones armónicas y el ruido normalmente asociado con otras fuentes de alimentación conmutadas de alta frecuencia. La serie XRF de generadores de rayos X incorpora un filamento flotante interno y un circuito de control de emisión de lazo cerrado para una regulación precisa de la corriente de emisión. También se proporciona monitoreo y control remoto de voltaje, corriente y corriente de filamento.

Typical uses of the XRF x-ray generator are:

• Inspección por rayos X
• Pruebas no destructivas

Electronic Component (Power Source)

XRF series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The XRF series is not intended to be operated by end users as a stand-alone device. The XRF series power supply can only be fully assessed when installed within a system, and as a component part within that system.
