Description
J Schneider AKKUTEC 2403 K, The battery buffered DC power supply of the series AKKUTEC is working according the stand-by parallel mode and ensures in connection with a lead-acid accumulator a safe continuous DC power supply in case of mains failure. The back-up time is depending from the state of charge of the accumulator and of the discharge current.
The power supply has the following features:
- Battery charger with I/U-charging characteristics
- Battery management by micro-controller
- Battery voltage tracking of the charging voltage by external sensor module (optional)J Schneider AKKUTEC 2403 K
