3. OPERATING MODES

The StromPi 2 has 2 operating modes UPS and Wide operation which are
explained in the following.
UPS-mode
The UPS-mode operates especially battery-saving. The wide range voltage
source is only charged in standby with 20 - 80 µA. This standby power
consumption is is very low so that the maintenance cycles of possible
bypass batteries / batteries can be accordingly long.
For one year of a standby operation, this circuit takes for example from
175 mAh to 700 mAh out of the wide range voltage source.
