Active Inverter Technology - battery-charging at its most intelligent
The Life-Extenders The innovative concept underlying Active Inverter Technology is based on the combination of a digital control circuit, dU/dt cut-off and an active-rectification inverter. The digital control circuit keeps the charging current and charging voltage constant throughout the charging operation, compensating for any fluctuations in the mains voltage so that the battery is charged gently and carefully. The technology behind the dU/dt cut-off stands out for its pro-active responsiveness. The special thing about this is the way in which it takes account of each battery’s age and state of charge and actively fine-tunes the programmed charging characteristic to match. The charging operation is finished at the ideal point in time - that is, when the voltage has reached its maximum. This prevents overcharging, reducing water consumption and prolonging battery life by as much as 50 %.
Lighter, more portable The Active Inverter Technology is what does the trick: By using smaller but highly active components, it brings about very substantial reductions in both the volume and weight of the units. As well as cutting down on the amount of space needed for stationary charging stations, this also makes for much “lighter” portability.
Thrifty Types The Active Inverter beats conventional inverters hollow. Whereas the latter achieve effi ciency ratings of between 78 % and 85 %, Active Inverter Technology from Fronius scores up to 96 %. This is part of the reason why every 7th charging operation effectively costs you – nothing! Better still: With the Active Inverter, you’ll be charging more quickly yet consuming less electricity. And the procurement costs will pay off equally quickly, too.
Maximum economy Active Inverter Technology prolongs the battery life. Longer maintenance intervals and lower logistics costs are the result. On top of this, Fronius battery chargers also have on-board capability – they can be permanently installed on or in the appliances or vehicles needing recharging. |
