SERIE ST FUENTES DE ALIMENTACIÓN DE ALTO VOLTAJE DE 12 KW

Las fuentes de alimentación de alto voltaje ST de 12 kW de Spellman están disponibles en polaridad positiva o negativa en 20 diferentes modelos con salidas en el rango de 1 kV a 225 kV. Un panel frontal con las funciones completas permite un control local sencillo, mientras que una interfaz analógica completa proporciona extensas funciones remotas. Las interfaces digitales estándar Ethernet y RS-232 simplifican la integración de la serie ST en el diseño de su sistema.

El robusto inversor IGBT de la serie ST es inherentemente tolerante a los fallos y es ideal para las aplicaciones demandantes como las de procesamiento de semiconductores y deposición en vacío. El usuario puede configurar muchas características de funcionamiento que se ajusten a sus requisitos particulares. Se pueden proporcionar más de 100 kW de energía configurando un chasis adicional en paralelo.

Digital Interface 

The ST features a standard 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 capability. Spellman pro­vides a GUI with the ST that allows the customer to both customize operational features of the ST while also pro­viding basic power supply operational features. Details of the ST’s digital interface capability are described in detail in the ST manual, downloadable via the link on the first page of this data sheet.
