AKKUTEC 2440

Battery buffered DC-UPS

Type      :   AKKUTEC 2440
Art.-No. :   NBPA P33G1M01

 

  

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

  • 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)

  • TEC-Bus on RS 232-Interface (optional module)
