J. Schneider AKKUTEC 4806

J Schneider AKKUTEC 4806, The accumulator buffered DC supply works according to the standby parallel principle and guarantees, in connection with a lead accumulator and for a certain time interval, a safe upkeep of the DC supply in case of a mains failure. The overall output current is split up between consumer supply and lead accumulator charge.

The power supply is characterized by the following properties:

  • Switching power supply with I/U charging characteristic
  • aktiv power factor correction (PFC)
  • Micro-controller supported lead accumulator management
  • RS232 for monitoring and parameterization
  • Temperature adjustment of the charging voltage by an external sensor
