Battery buffered DC-UPS

Typ       :   AKKUTEC 2410-0
Art.-No. :   NBPAN33G1M01


Short Description

The accumulator buffered DC supply works according to the standby parallel principle and guarantees, in connection with a lead accumulator and for a certain amount of time, a safe backup operation 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 back-up time depends on the state of charge of the accumulators and the discharge current. 

The power supply is characterized by the following properties:

  • Primary switched power supply with I/U charging characteristic
  • Active power factor correction (PFC)
  • Micro-controller supported lead accumulator management
  • RS232 for monitoring and parameterization
  • Optionally temperature tracking of the charging voltage by an external sensor
  • Optionally display and control panel for mount-in cabinet door or built up
