J. Schneider AKKUTEC 2440

Description

J Schneider AKKUTEC 2440, 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)
