Note
:
1.
At low input voltage the UPS recharging capability increases and load decreases (up
to the maximum capacity indicated).
2.
For 70kW module, recommend 240V battery voltage installed. Output power
wattage is 80% of rated power at 192V battery voltage. 90% of rated power at
216V battery voltage.
