Charging Current
0.8/3.3 A max
Ambient Temperature - 20°C till + 50°C. Automatic reduction of power at increased
ambient temperature.
Cooling
Natural convection. Do not cover the charger.

*) The back current drain is the current that the charger uses from the battery when the
wall plug is not connected. The reverse current of the MULTI US 3300 is very low and
corresponds to 1 Ah per month.
**)The ripple wave describes how many disturbances are exhibited by current and volt-
age. A rippled voltage can cause damage to other equipment connected to the battery.
The MULTI US 3300 supplies voltage and current with very low voltage rippling. This
increases the life of the battery and ensures that equipment connected to it will not be
damaged.
