systems from poor quality utility power, complete loss of power,
or other associated problems.
Electrical interference exists in many forms, causing problems in
AC power, from lightning, power company accidents and radio
transmission motors, air conditioners, and vending machines.
Protection of sensitive electrical equipment is vital to protect
against power outages, low or high voltage conditions, slow
voltage fluctuations, frequency variations, differential and
common‐mode noise, transients, etc.
To prevent power line problems from reaching critical systems
causing damage to software, hardware, and equipment
malfunctions, the UPS maintains constant voltage, isolating critical
load output and cleaning the utility AC power.
Line‐Interactive Technology
A line‐interactive technology UPS provides basic power protection
and Automatic Voltage Regulation (AVR) to the load when AC
input power is available. When AC input power is unavailable, the
line‐interactive UPS will switch to batteries to supply the load with
power. In the event that the power failure lasts longer than the
UPS backup time, the UPS will shut down avoiding battery
damage. When the input AC voltage returns, the UPS will
automatically return online to recharge the batteries.
 AC input flows into and through the AVR to the load.
 When AC input varies outside the acceptable specification,
the AVR switches taps on the transformer to better
regulate the output.
 If AC input power fails, the inverter turns on an supplies
power from the batteries to the load.
