Buffer module for DC power supply FEAS GmbH
12 Vdc, 24 Vdc, 48 Vdc, 5 to 25 A

Application
The buffer module can be connected directly in parallel to the regulated DC circuit of a DC-power supply or a DC-consumer, in order to buffer load currents during line voltage faults, peak loads or switching operations.
Through this, interferences at controls, caused by short blackouts, can be avoided.

Functional principle
The buffer module stores energy as long as the DC power supply
voltage is available. In case of a power failure the buffer module delivers the energy controlled to the consumer. Because most blackouts are shorter than 0.2 seconds and can be bypassed with the buffer module and the reliability of the complete system is considerably improved.

Extending the retention time
After a power down or a line voltage failure the load current is taken over by the buffer module for a certain time. Thus for example operations can be finalized controlled and process data can be stored, to allow controlled restarts.
