AKKUTEC 2403 with DC-Input

Battery buffered DC-UPS

Type      : AKKUTEC 2403DC
Art.-No. : NBUA 2403 DC-0523G01 

Short description

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)
