DC-DC 高压电源
集形状、贴装和功能于一体的设计：
斯派曼UM8-40 系列的印刷电路板可贴装高压模块，集形状、贴装和功能于一体，可替代目前市面上使用的电源，同时具有更多的功能，价格更具有竞争优势。使用专有的功率转换技术和斯派曼六十多年高压经验，这些基于SMT 高压模块与竞争产品相比，性能更好、可靠性更高、与系统集成更方便、价格更低。
先进的功率转换拓扑技术：
UM8-40 转换器使用专有的零电压切换功率转换拓扑技术，使其具有卓越的效率及低噪声与低纹波。与传统转换拓扑相比辐射大大减少。有效地降低屏蔽邻近电路的需求，甚至不需要屏蔽。
高压输出通过使用铁氧体磁芯的高压升压变压器产生，运用一组半波科克罗夫特—瓦尔顿电压倍增器来获得指定的高压输出。
由于具有固定的高频转换率，其输出电容很小，因此存储能量最低。通过使用宽大的额定浪涌限流电阻和一个快速电流环路，所有电源均受到全面的电弧和短路保护。
控制和调节：
实际输出电压通过一个高阻抗分压器来输出一个电压反馈信号. 电流反馈信号是通过一个电流传感电阻在高压输出电路的低端返回输出。这两个精准的对地参考反馈信号除外部监测用途外习惯于精确地调控电源。
UM8-40 独特的转换拓扑技术，使得电源能够满电流工作在低阻抗负载甚至一个短路电路中。标准的电源限制在最大额定输出电流的103%。
标准接口：
UM8-40 系列接口提供电流编程能力、正极性、带缓冲、低输出阻抗，电压和电流监测信号( 零至+4.64Vdc 等于零至额定满量程)。还提供电压编程输入，0 至+4.64Vdc 等于0 至100% 的额定电压。
电流编程允许用户去设置这个电源的电流限制， 从0 至100% 的最大额定电流均可。此功能对于需求小于满输出电流是有用的，如在保护一个敏感的负载的情况下。
缓冲的低阻抗电压和电流监测信号能直接驱动外部电路，同时将负载和传感效应降至最低。这些功能节省了用户的费用和外部接口缓冲电路的实现，同时提高了整个信号的完整性。
标准接口由一排13 个引脚构成，引脚间距为0.1˝。一个传统接口( 7 个引脚，引脚间距为0.2˝ ) 是与目前可用的商业制成相配的，电源能通过订购“L” 选项提供。
机械和环境的考虑因素：
UM8-40 系列是固态封装的、可安装的印刷电路板、塑料壳转换器。所有电源使用基于硅灌封材料封装，比环氧树脂封装技术重量更轻。使用独立的、非接地的2-56 机械螺丝把模块安全地安装到印刷电路板，缓解了接口引脚承担的一些应力。安装板、支架和法兰安装选项也是可用的。高压输出是通过一根最小长度为 36˝ (914.4mm) 的高压线提供。
合规认证：
符合EMC 2004/108/EC 指示和低压2006/95/EC 指示。UL/CUL 认证，文件E227588。符合RoHS。
