AKKUTEC 2403C

Short description

The battery buffered DC power supply is working according 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 supply of the loads and charging of the batteries.
