Mass Spec Power Supply

  斯派曼的 MI1.5PN24 是一款良好调节的高性能 DC-DC转换器，具有浮地 1.5kV @ 6.5mA 输出，它的工作范围为300V-1500V。输出是隔离的；这允许连接负载的+Ve, -Ve或可切换极性，并且脉冲电流被包含在规定的路径内，减少噪声和干扰信号。MI1.5PN24 低输出纹波规格使得它非常适合于质谱应用中的脉冲器使用。此模块封装在屏蔽金属外壳中并且高压输出时通过两个固定的电缆提供。MI1.5PN24 具有一个大的、高质量的电容和坚固的输出网络，这允许高能脉冲负载连续供电而不需要电压骤降或损坏到单元电路。此单元有远程 0-10Vdc = 0-100% 额定电压编程和电压监测。一个 TTL 兼容的使能信号提供了简单的高压输出控制。
