Input Voltage Operating and Derating
When there is an AC input out of range warning in the lower
range between 90–108 Vac, the Truecharge™ 2 Battery
Charger derates to 80% of maximum current.
However, when AC input increases above 108 Vac up to
255 Vac, maximum current returns to 100% capacity.
Furthermore, the Truecharge™ 2 Battery Charger will
continue to operate at 100% of maximum current, even while
there is an AC input out of range warning in the upper range
between 256–265 Vac.
