The Different Type of UPS Systems Available
Public utility supplied AC voltage is seldom a steady 120V AC. Power can dip down to around 100V, and peak into the 130V region without major problems. However, if power falls outside this range, you can lose computer data and cause damage your hardware. To prevent under-voltage “brownouts” and over-voltage “power surges”, some on-line UPS systems can correct utility power ranging from 85V into the mid-130Vs. They also keep loads safe from spikes, or those brief moments when lightning or other...
