Three Phase Automatic Battery Chargers

The ABC-series of three phase chargers are a completely solid state, automatic and of the constant voltage type having:

AC voltage compensation
DC voltage regulation
Full current limit
Filtered DC output (ABC32)
Three phase AC input

Two rate charging is standard. A control switch allows selection of float-automatic, or high rate charge. With optional Auto-Charge, in the automatic mode, the charger will high rate charge the battery whenever it is discharged.

The three phase charger will raise the voltage to the high rate setting and maintain this level for a timed interval. Recharge of the battery is accomplished without excessive over or undercharging.

The ABC-series float chargers are fully current limited. If current demands exceeds the chargers rating, the output voltage drops rapidly, protecting the charger and the system to which it is connected. The chargers fuses or breakers will not trip during such overload conditions.
