AKKUTEC 4810

Battery buffered DC-UPS 

Type      : AKKUTEC 4810
Art.-No. : NBPA 0347G01007

 

Short Description

The battery backed up DC power supply in the AKKUTEC range uses the standby-parallel principle of operation and, in conjunction with a lead accumulator, ensures that the DC power supply is reliably maintained in the case of a mains power failure. The total output current is shared between the supply of the load and the charging of the lead accumulators. The back-up time depends on the state of charge of the lead accumulator and the discharge current.

The power supply has the following features:

  • Switched primary, switched power supply with I/V charging characteristic
  • Active power factor correction (PFC)
  • Microcontroller-based battery management
  • Temperature compensation for charging voltage by means of external sensor module (optional module)
  • Display and control panel for switch cupboard door installation or surface mounting (Option)
