AKKUTEC 4810

Battery buffered DC-UPS 

Type      : AKKUTEC 4810
Art.-No. : NBPA 4810-0347G01

 

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 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)
