The AT-UPS2000S-LCD UPS is equipped with a number of advanced technologies for active mains monitoring
Line-interactive power supplies analyze the voltage, frequency and angle of phase shift in real time, as well as filter the voltage transmitted to connected devices. When a network failure is detected, the power supply immediately switches to autonomous operation mode and continues to power the equipment using the energy stored in the internal batteries
The device works with power supplies with active power factor improvement system (APFC)
