Switch-Mode Battery Chargers
Model: ABC31SM
For charging standby & online batteries
The new Three-Phase Automatic Battery Charger features a switch-mode design for high efficiency. The unit also features:
- AC voltage compensation
- DC voltage regulation
- Full current limit
- Filtered DC output
Three rate charging is standard. The charger will raise the voltage to the high rate setting and maintain this level for a timed interval at which point it will reduce to a safe float. Recharge of the battery is accomplished without excessive over or under charging.
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.
