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.
