DC-UPS with Batteries

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)
