在研制“外推电离室微机控制及数据采集系统”时,为了节约经费借用多道谱仪中的Canberra 3105型NIM插件电源。由于没有接口电路,它不能直接用于计算机控制。本文主要介绍3105型高压电源的极性切换及微机控制的接口电路。 3105型电源是一个直流变换器,它采用2000型NIM插件±12V和±24V电源变换成±5000V高压。此电源的正、负极性切换,是靠一块印刷电路板用人工拔出后转180°再插
In the development of “extrapolation ionization chamber microcomputer control and data acquisition system”, in order to save money to borrow multi-channel spectrometer Canberra 3105 NIM plug power. Since there is no interface circuit, it can not be used directly for computer control. This article mainly introduces the 3105 high voltage power supply polarity switching and computer control interface circuit. The Model 3105 is a DC-DC converter that converts to ± 5000V high-voltage using ± 2000V ± 24V ± 24V power supplies using the Model 2000 NIM plug-in. The power of positive and negative polarity switching, is by a printed circuit board manually pull out after the turn 180 ° and then plug
