!important;">电源维修后电压会发生改变，须再调整电压。如果调整失误，会损坏后面的电路板，引起不必要的损失。</span></p><p style="max-width: 100%;min-height: 1em;box-sizing: border-box !important;word-wrap: break-word !important;"><br

style="max-width: 100%;font-size: 15px;box-sizing: border-box !important;word-wrap: break-word !important;">选用市场上旧的二手电源可以代换。一是价格便宜，二是性能相对好(旧CT的拆机件)。</span></p><p style="max-width: 100%;min-height:

!important;">因为一旦散热不良即引起故障(电源风扇不转或进风口灰堵)，所以平时要加强设备的维护保养，减少电源故障的发生。</span></p><section class="" style="max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;"><p
