J. Schneider AKKUTEC 2412 VdS

J Schneider AKKUTEC 2412 VdS, The battery buffered DC power supply is working according to the stand-by parallel mode and ensures in connection with a lead-acid accumulator a safe continuous DC power supply during a determined time interval in case of mains failure. The total output current is shared between the supply of the loads and charging of the batteries.
