机房稳压电源通常是1280元，电源接上负载后，通过采样电路获得输出电压，将此输出电压和基准电压进行比较。如果输出电压小于基准电压，则将误差值经过放大电路放大后送入调节器的输入端，通过调节器调节使输出电压增加，直到和基准值相等；如果输出电压大于基准电压，则通过调节器使输出减小。

一般的机房的稳定电源的价格也就是3000上下！我建议你资金够得话可以用在线式的，不够就只好每台电脑配一个后备式的！

你好，1、确定额定负荷大小：电脑目前通常标配负荷为400W/台，考虑硬件更新因素，按400W/台考虑比较合理。则81台电脑总装机负荷为400×81＝32.4KW。2、确定计算电流的大小：[32.4/(0.22×0.7×3)]×0.75＝52.6A。所以，就配置的稳压电源总负荷为32.4×1.2＝38.8＝40KW；额定电流为52.6×1.2＝63.12＝65(A）上述参数仅供参考，对于重要机房，建筑采用UPS不间断电源供电方式，UPS属于在线式后备电源，它具有稳压、整流等作用。
