用于图像增强器的模块化高压电源
斯派曼新的DGM945 高压电源适用于图像增强器应用，为高压功率转换技术设立标准。
DGM945 也有输入来允许测量光电阴极电流和吸气剂电流。光电阴极测量有两个范围：敏感范围：0 至50nA 和标准范围：0 至15μA。敏感输入习惯于提供一个带0.1V/nA 灵敏度的监测输出。吸气剂输入允许吸气剂电流的测量，表明图像增强器球管仍保持良好的真空和没有气体导致电离。
通过本地测试点或串行接口可以监测所有的输出电压。此电源可以存储多达八种操作模式。输出电压在每个模式下通过电源内置的旋转编码器或串行接口任一方式是独立可调的。
DGM 系列能适合多路选择的多种输出电压的特殊需求并在紧凑的封装里功率容量，使其完美适合OEM 用户。
典型应用:
- 放射学
- 心脏病学
- 神经放射学
- 夜间监视
- 无损X 射线检测
- 图像增强器
