FUENTES DE ALIMENTACIÓN DE ALTO VOLTAJE DE 6 KW
Las fuentes de alimentación de alto voltaje de la serie STR de 6 kW de Spellman están disponibles en polaridad positiva o negativa en19 diferentes modelos con salidas en el rango de 1 kV a 150 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 STR en el diseño de su sistema.
El robusto inversor IGBT de la serie STR 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.
Aplicaciones típicas:
- Implantación por rayos de iones
- Procesamiento de semiconductores
- Carga de capacitores
- Transmisores de RF de alta potencia

Digital Interface
The STR 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 STR that allows the customer to both customize operational features of the STR while also providing basic power supply operational features.

Arc Intervention
Spellman’s STR power supplies have an arc intervention feature that senses arc currents via a fast acting current sense transformer. The purpose of the arc intervention circuitry is to prevent power supply damage from continuous, long term arcing. The factory default configuration will trip off the unit with an Arc Fault if 4 arcs occur in a 10 second time period. Customers can change basic arc intervention parameters (Arc Count, Arc Quench, Reramp Time, and Window Time) within preset limits via the digital interface; customized units can be provided for unique arc prone environments, contact Spellman for details.

Electronic Component (Power Source)
STR 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 STR series is not intended to be operated by end users as a stand-alone device. The STR series power supply can only be fully assessed when installed within a system, and as a component part within that system.

*Substitute “P” for positive polarity and “N” for negative polarity. Polarity must be specified at time of order.
1-10kV units are inherently reversible by design requiring an internal wiring change to swap polarities. Intermediate voltage units are available by special order.
