• 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.
2.2 Efficiency 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 on-line modes is achieved automatically and in
accordance with the conditions of the utility power. On-line mode may be used during
times of utility power irregularities. The bypass mode should be used when power flows
smoothly in order to obtain the greatest efficiency. Irregularities can be detected in less
