Sine-wave UPS

Line-Interactive (Offline) Sine-wave UPS with AVR

In a line Interactive UPS (earlier known as OFFLINE ups), the load is connected to the mains supply which is stabilized directly. The moment the power fails the load will be switched over to the output of the inverter. There is a definite switch over time in Offline UPS which can be between 5ms to 20ms. Upto 20ms, interruption in power will not be felt while using the computer because the SMPS input capacitor, will supply power to the computer.

Line Interactive UPS is a variant of Offline UPS. In a Line Interactive UPS there is only one transformer which, when the mains is present is used for stabilization of output and also delivers power for charging the battery. When power fails the function is reversed and used as inverter transformer.

This kind of a design reduces the overall cost and also is more efficient. It must be noted the inverter remains OFF when usable utility power is available.

All these are designed based on Microprocessors to give enhanced reliability and features. Some of the unique features are Automatic Voltage Regulation (AVR) and advanced charger.
