J. Schneider AKKUTEC 2420 3ph

J Schneider AKKUTEC 2420 3ph, 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 power supply has the following features:

  • Primary switched power supply with I/U-charging characteristics
  • active power factor correction (PFC)
  • Battery management by micro-controller
  • Battery voltage tracking of the charging voltage by external sensor module (optional)
  • Display- and control panel for mount in cabinet door or module (optional)
  • redundant operation or Master-/Slave-operation possible
