UPS Line Interactive is a reliable, qualitative and economical solution to protect and provide uninterrupted supply to the loads.

-How Line Interactive UPS works?

UPS VI (Voltage Independent)
With this technology known as line interactive technology, the variations of the supply voltage are stabilized by means of adjusting devices keeping them within the limits of normal operation.
In normal operating mode, the load is powered from the mains through an AVR (Auto Voltage Regulator) circuit. This device corrects voltage variations within its capacity for regulation, returning the voltage to its default values. When the variations in the power supply are not within the capacity for regulation of the AVR circuit, the inverter intervenes and through the stored energy in its batteries it ensures the continuity and quality of the power supply. The transition from stabilised mains to inverter supply takes place in about 2-6 ms and the voltage generated by the inverter can be of a sinusoidal type or stepwave (square-wave) type depending on the UPS model.
