4kW High Voltage Power Supplies

Высоковольтные источники питания серии STA мощностью 4 кВт, поставляются с положительной или отрицательной полярностью. В состав серии входят 15 моделей с диапазоном выходных напряжений от 1 до 70 кВ. Полнофункциональная передняя панель позволяет с легкостью управлять источником локально, а развитый аналоговый интерфейс обеспечивает комплексное дистанционное управление. Стандартный интерфейс Ethernet и цифровой интерфейс RS-232 упрощают интегрирование блоков STA во внешние системы. Инвертор на биполярных транзисторах (IGBT) конструктивно устойчив к отказам и идеален при повышенных требованиях, например, в полупроводниковой промышленности или при вакуумном напылении. Множество рабочих функций настраивается в зависимости от требований пользователя.

Типовые применения:

• Ионное легирование
• Обработка полупроводников
• Электронно-лучевая сварка
• Зарядка конденсаторов
• Радиопередатчики высокой мощности
• Электростатические электрофильтры
• Рентгеновские системы

Digital Interface

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

Arc Intervention

Spellman’s STA 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)

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