直流-直流高压电源

集形状、贴装和功能于一体的设计:

斯派曼UM 系列的印刷电路板可贴装高压模块,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:

UM 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。

高压输出使用了一个铁氧体磁芯的高压升压变压器供应输出电路。电源在1kV 或更高的运用一组半波科克罗夫特—瓦尔顿电压倍增器去获得指定的高压输出,而较低的电压电源使用一强健的整流和滤波电路。

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,除了外部监测用途外,还用于精确地调节和控制电源。

UM 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:

UM 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( 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。

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:

UM 系列是固态封装的、可安装的印刷电路板、塑料壳转换器测量只有2.97˝ X 1.5˝ X 0.83˝ (75.4mm X 38.1mm X 21.1mm)。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。使用两颗独立的、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。提供安装板、支架和法兰安装选项。

合规认证:

符合EMC 2004/108/EC 的标准和低压2006/95/EC的标准。UL/CUL 认证,文件E227588。符合RoHS。
