13.8V 8A power supply with 12V lead acid battery charger (UPS function).
Output voltage can be adjusted from 11 to 14.5V, but even the battery output voltage will change, so it's better to keep 13.8V output, 8A max, so the battery voltage will be 13.4V that is the optimal voltage to get a long battery life.
Input voltage can be selected, 230V (200-240V) or 115V (100-120V), 50 or 60Hz.
Overload protection when drained power is between 110% and 150% of max power.
Battery protection: disconnect battery output when battery voltage is under 11V. Stop charging when battery is full, to provent overcharging.
Using an additional DC/DC converter 12 -> 5Vdc 3A, it's possible to supply a Raspberry PI with stable voltage even in case of power outage, thanks to the backup battery.
Suitable for domotic systems, to get it working even in case of power outage.
