奥斯达蓄电池6GFM200(12V200Ah)充满电能存2.4KW/h的电量，如果100W的灯泡使用可以供电22个小时，由于计算机机房设备有各种开关电源类的非线性负载及各类打印机负载，这些负载冲击电流大，如果供电UPS容量过小，长期重载运行，容易出现波形失真，而且易造成输出末级功率器件过流，加上重载引起的发热量，对系统可靠性明显不利。对于大功率UPS，一般建议容量使用率控制在0.6~0.8。

　　当然UPS容量也不宜过大，UPS带很小的负载虽然有利于可靠性，但过度轻载运行，一则浪费了投资，二则在市电长时间停电时，电池一直小电流放电，容易发生深度放电引起损坏。

Mr Starr battery 6 gfm200 v200ah (12) is full of electricity saving 2.4 KW/h, if use 100 w bulb can supply 22 hours, because there are all kinds of switch power supply computer room equipment class of the nonlinear loads and all kinds of printers load, the load impact current is big, if the power supply UPS capacity is too small, heavy service for a long time, it's easy to have a waveform distortion, and easy to cause the output level at the end of the power device, over current, plus the calorific value caused by overloading, adverse to the system reliability is obvious.For high-power UPS, it is generally recommended to control the capacity utilization rate at 0.6~0.8.

Of course, the UPS capacity should not be too large, although the UPS with a small load is conducive to reliability, but too light load operation, a waste of investment, and two in the power failure for a long time, the battery has been small current discharge, prone to deep discharge damage.
