•An input filter reduces transients on the main supply.
•For maintaining full battery charge, AC power is rectified and regulated in the rectifier feeding power to the inverter and battery converter.
•DC power is converted to AC in the inverter and passes it on to the load.
•Power to the load is maintained from the battery during a power failure.
•The converter increases voltage for the inverter as required.
2.2Efficiency Optimizer Function
The Efficiency Optimizer function is a new feature for the UPS that increases the cost effectiveness of the UPS by minimizing power losses and reduces power consumption. Alternating between bypass and
