一旦输出短路或严重过载时间超出几百毫秒将二极管(通常为肖特基二极管)过热损坏;其二,当由于某种原因,比如人为关闭,使开关振荡电路停止工作,负载端仍然有电压存在,只是比输入端低一个二极管的管压降而已,这时输出仍会消耗能量。除此之外,如果该残存电压低于负载稳态工作电压范围,将使电路处于不确定状态。对于输出电流相对较小的应用(小于5A),利用单片电流控制器和高端电流取样技术,上述两个问题都可以很好地解决。在这些电路中,二极管被一同步整流开关三极管取代,因此通过关闭内部开关三极管就可把输入输出通路截断,这样一来,负载端对输入端来说就呈高阻状态,而这正是所希望的结果。在正常工作状态,电路内部的高端取样电阻对负载电流周期性地进行采样。

也就是人们常说的普通晶闸可控硅可控硅管,它是由四层半导体材料组成的,有三个PN结,对外有三个电极〔图2(a)〕:层P型半导体引出的电极叫阳极A,第三层P型半导体引出的电极叫控制极G,第四层N型半导体引出的电极叫阴极K。从晶闸管的电路符号〔图2(b)〕可以看到,它和二极管一样是一种单方向导电的器件,关键是多了一个控制极G,这就使它具有与二极管完全不同的工作特性。以硅单晶为基本材料的P1N1P2N2四层三端器件,起始于1957年,因为它的特性类似于真空闸流管,所以上通称为硅晶体闸流管,简称晶闸管T,又因为晶闸管初的在静止整流方面,所以又被称之为硅可控整流元件,简称为可控硅SCR。在性能上,可控硅不仅具有单向导电性。输入阻抗为250W〗18.功率消耗:不大于30W19.正常工作:温度范围:0~50°C湿度范围:10~85%R?H20.电源电压:220V;50Hz21.外形尺寸:144′144′200mm22.开孔尺寸:138′138mm工作原理编辑每路输入经程控放大,24位分辨率A/D转换,光电隔离送至单片机处理。从而了各输入通道之间的,了输入通道与CPU之间的。使用高精度数字温度传感器,进行热电偶的冷端温度补偿。为了长期性,本记录仪放弃了的用电位器放大倍数及零点的,代之以程序调校法,并实现了放大倍数的程控放大。出厂前厂方对各项参数均已调试完成。用户可通过键盘设定对误差进行平移校正。
