The ABC-series of float 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 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 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.

Standard Features

  • Conservative component selection and design assures long life
  • LEDs for AC-ON, and high rate charge AC input 3-pole breaker
  • AC and DC surge protection Float / high rate control switch DC voltmeter & ammeter 2% Precise voltage regulation Fully current limited
  • AC input breaker and DC output fuse Reverse battery protection
  • Natural convection cooling Modular construction

Options

  • DC 2-pole breaker instead of fuse Precision metering
  • Extra filter (Use ABC32)
  • Battery temperature compensation AC failure alarm relay
  • Multi-Alarm Monitor includes four alarms & LEDs with common relay for High DC volts, Low DC volts, Rectifier failure and Ground fault.
  • Separate alarm relays may be specified. Precision metering
  • Auto-Charge Control or manual timers Audible alarm
  • Drip Shields
  • CE compliance and marking Many other accessories available
