Nominal: 12 V 14.4 VDC
Ripple**
Max 50 mV rms, max 0.13 A.
Charging Current
3.3 A max
Ambient Temperature
- 4°F to + 122°F. Automatic reduction of power at
increased ambient temperature.
Cooling
Natural convection. Do not cover the charger.
Charger type
Four step fully automatic with pulse maintenance mode.
Type of batteries
All types of lead-acid batteries. (WET, MF, AGM, Ca/Ca)
Battery Capacity
Max 90 Ah

6 1/2 x 2 3/8 x 1 1/2 inches (L x W x H)
Weight
1.1 lbs
*) 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 US 3300 Corvette (model
1051) is very low and corresponds to 1 Ah per month.
**)The ripple wave describes how many disturbances are exhibited by current and
voltage. A rippled voltage can cause damage to other equipment connected to the
battery. The US 3300 Corvette (model 1051) 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.
