AKKUTEC 1220

 

DC-UPS with Batteries

Type         :  AKKUTEC 1220-0

Art.-No.   :   NBPA0347G01002

 

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 total output current is divided between supplying the load and charging the lead-acid battery. The buffer time depends on the state of charge of the lead-acid battery and the discharge current.

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)
