60-125W 高压电源

集形状、贴装和功能易用性于一体：

斯派曼UMW 系列的高压模块，为用户提供集形状、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，此基于SMT 高压模块与竞争产品相比，性能更好、与系统集成更方便、价格更低。

先进的功率转换拓扑技术：

UMW 转换器使用专有谐振功率转换拓扑技术，使其具有卓越的效率及低噪声和低纹波输出。与传统切换拓扑技术相比辐射大大减少，有效地降低屏蔽邻近电路的需求，甚至不需要屏蔽。

高压输出使用了一个铁氧体磁芯的升压变压器供应高压输出电路。电源采用一个妥善安排的低电容量科克罗夫特—瓦尔顿电压倍增器去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放置在高压输出电路的低端返回而产生。这两个精准的对地参考反馈信号用于精确地调节和控制电源输出。这些精确的和校准的信号是用于外部监测目的。

UMW 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%。

标准用户接口：

UMW 系列提供一个标准的客户接口，提供电流编程能力和正极性、带缓冲、低输出阻抗电压和电流监测信号(0 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。

机械和环境的考虑因素：

UMW 系列是模块化的金属板封闭转换器，测量尺寸为8.00˝ X 4.50˝ X 1.075˝ (203mm X 114mm X 27mm)。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。电源的安装是通过使用底部安装螺柱或螺纹盲插入来完成，根据所订购型号而定。
