我台机房配备的一台燕标后备式UPS不间断电源,投入运行还不到两年时间就出现了故障。故障现象:在没有接通市电的情况下,开机后UPS没有任何反应;但在接通市电后,UPS控制面板中的红色指示灯不停地闪烁着,不过亮度没有达到正常的状态。用万用表检查测试时发现UPS有交流电源输出,输出电压很低而且数值不稳定;用正常的方式充电后,这种现象还是不能消除。
I Taiwan room equipped with a Yan standard backup UPS uninterruptible power supply, put into operation in less than two years appeared on the fault. Symptom: In the case of not connected to the electricity, the UPS did not respond after boot; but after the power is switched on, the red light in the UPS control panel constantly flashing, but the brightness did not reach the normal state. Check with a multimeter found that the UPS has AC power output, the output voltage is low and the value is not stable; with the normal way of charging, this phenomenon still can not be eliminated.
