battery discharge, and as soon as voltage comes back, the UPS will automatically charge up
and start recharging the batteries.
As shown in fig.1 block diagram:
An input filter reduces transients on the mains
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 passing it on to the load.
Power is maintained from the battery during a power failure.
The converter increases voltage appropriately for the inverter.

Efficiency Optimizer function
The Efficiency Optimizer function is a new feature for the UPS adding cost effectiveness,
minimizing power loss and reducing 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 intermittent power supply, and bypass
mode when power flows smoothly in order to obtain greatest efficiency. Irregularities can be
detected in less than a second, and on-line mode reactivated immediately. Switching back to
online mode occurs when input voltage is outside ±10% or nominal (±15% selectable), when
input frequency is outside of ±3Hz or when no input line is available.
Although high efficiency is standard, the default operation is in on-line mode. Bypass can be
