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
