INSTRUMENTOS DE MEDIÇÃO E CALIBRAÇÃO Fontes Alimentação CC

A nova série EVA da Spellman foi projetada especificamente para aplicações exigentes de revestimento por feixe de elétrons. Um painel frontal completo oferece controle local fácil, enquanto uma interface analógica permite funções remotas. As interfaces digitais Ethernet e RS-232 incluídas simplificam a integração da série EVA ao design do seu sistema.

O design robusto do inversor IGBT da série EVA é inerentemente tolerante a falhas. A seção proprietária de baixa capacitância, armazenamento de baixa energia e saída de alta tensão é ideal para as condições de carga dinâmica e falhas encontradas nas aplicações de revestimento. Os tempos rápidos de recuperação de arco (<2ms) minimizam a interrupção do processo. O usuário pode configurar muitos parâmetros operacionais para atender seus requisitos específicos.

Uma fonte de canhão de filamento está disponível como opção. O EVA pode suportar 1, 2 ou até 3 canais de energia para o canhão de filamento, fornecendo flexibilidade e custo-benefício sem precedentes.

Digital Interface

The EVA features a standard RS-232 and Ethernet digital interface, simplifying power supply communication require­ments saving the user time and money, while enhancing functionality and overall capability. Spellman provides a GUI allowing customization of operational features while also providing basic power supply functionality and control via a sample simulated front panel.

Arc Intervention

Spellman’s EVA power supplies sense arc events via a fast acting current sense transformer. The arc intervention cir­cuitry prevents power supply damage from continuous, long term arcing. Customers can change arc intervention para­meters (Arc Count, Arc Quench, Reramp Time, and Window Time) within preset limits via the provided GUI. Customized units can be configured for unique arc prone environments, contact Spellman for details.

Additional High Voltage Output Connectors

Spellman’s EVA is designed to provide 1, 2 or 3 parallel configured high voltage output connectors. The standard unit provides one high voltage output connector. If you intend to use the EVA in a multi channel application but want to utilize your own filament power supply, this factory installed option provides the additional high voltage con­nections required. Hardware Option HV2 provides two high voltage output connectors, while Hardware Option HV3 pro-vides three high voltage output connectors.

Multiple beam control units can be provided, allowing 1, 2 or 3 separate electron guns to be independently operated.

Each beam control unit consists of a beam controller and a gun output box. The beam controller is a 1U rack-mounted chassis containing the filament power, control and emission regulation circuitry. The gun output box contains the high frequency filament transformer which is referenced to the high voltage output potential. This box should be mounted close to the electron gun to minimize the length of the high current filament connections. The box also contains electron gun emission current monitoring circuitry and provides a feedback signal used to regulate the electron gun emission current.

Each beam control channel, if operated alone, can utilize 0 to 100% of the rated emission current capacity. When two or three beam control channels are used at the same time, the total system emission current capacity remains the same. Individual channel programming must be done such that the total current does not exceed the system’s total emission current available.
