2.3—Power Flow
In the
INTegral Line-Interactive UPS
, AC utility power flows through two (2) main loops: the AC loop and the battery
charging loop (
Figure 1
).
2.3.1
—Normal Power Mode
When functioning normally, the system will charge batteries to operate when utility power is unstable. Battery
charging from the utility supply provides a cost-effective means of providing reliable, uninterruptible power and
increasing UPS efficiency
—saving you money.
In the AC loop, the power comes from AC utility input such as a wall outlet and passes through a static switch to
support power to the load, so long as power is clean and reliable.
In the battery charging loop (
Figure 2
), an AC/DC converter changes AC utility input voltage into DC power, which
charges the unit’s batteries.
