Spellman MPS20W DC-DC 20W 高压电源

斯派曼MPS20W 系列是一个20W 高压模块，输出电压范围从1kV 至10kV。

MPS20W 系列使用了斯派曼线性的混合拓扑技术和开关模式功率转换技术，提供低噪声具有更高效率的高性能产品设计。MPS20W 系列从紧凑的封装产生出卓越的纹波和稳定的性能规格。此外MPS20W 系列标配，用于电压编程信号的差分放大器输入，可更好地隔离外部噪音并解决任何偏移问题。另外输出电压可以通过内部的电位器预设。

通过15 针D 型连接器提供一个全功能的远程用户界面作为标准。输出电压具有电弧和短路保护，电源输入配有限流器。

斯派曼专有的高压技术与SMT 电路相结合造就了一个超紧凑并重量轻的模块，可提供正的或负的极性输出，可完美地适合OEM 应用。
