AKKUTEC 2402 C


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 power supply is characterized by the following properties:

•           Primary switched power supply with I/U charging characteristic

•           Micro-controller supported lead accumulator management

•          Temperature adjustment of the charging voltage by an external sensor.
