6kW 高压电源

Spellman STR 系列 6kW 高压电源提供 19 种正/负极性的不同型号,输出范围为 1kV 至 150kV。功能齐全的前面板可轻松实现本地控制,广泛的模拟接口则提供全面的远程功能。标准以太网和 RS-232 数字接口简化了 STR 与系统设计的集成。

STR 强大的 IGBT 逆变器具备固有的容错能力,是半导体加工和真空沉积等严苛应用的理想选择。用户可以根据自身的具体要求来配置多种操作功能。


  • 离子束注入
  • 半导体加工
  • 电子束焊接
  • 电容器充电
  • 高功率射频发射器
  • 静电除尘器
  • X 射线系统 

STR 搭载标准的 RS-232 和以太网数字接口。利用这些标准数字接口可以大大简化电源接口要求,为用户省时省钱,同时增强功能和整体能力。Spellman 为 STR 提供了 GUI,GUI 让用户能够自定义 STR 的操作功能,同时也提供基本的电源操作功能。STR 手册中详细介绍了 STR 的数字接口功能,通过本数据表第一页上的链接可下载该手册。

Spellman 的 STR 电源具有电弧干预功能,可通过快断式电流感应变压器感应电弧电流。电弧干预电路的目的是防止电弧长期连续放电而损坏电源。如果在 10 秒内发生 4 次电弧,则出厂默认配置将对出现电弧故障的装置予以跳闸处理。客户可以通过数字接口在预设限值内更改基本电弧干预参数(电弧计数、灭弧、重新斜升时间和窗口时间);客户也可以为独特的电弧环境提供定制装置,详情请联系 Spellman。

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. Details of the STR’s digital interface capability are described in detail in the STR manual, downloadable via the link on the first page of this data sheet.

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.
