The output section of the buffer module is fully controlled and is equipped with an electronic current limitation. A
current overloading of the buffer module cannot happen, independent of which sizes of power supplies are used on
the input of the buffer module.
current overloading of the buffer module cannot happen, independent of which sizes of power supplies are used on
the input of the buffer module.
The current limitation works in a switching mode which reduces the power losses and heat generation to a minimum.
Output in normal mode:
In normal mode (and also in charging mode), the output voltage is slightly lower as the input voltage. The output
voltage follows the input voltage reduced by the input to output voltage drop.

by the buffer module. It can be higher if the supplying
source has a higher ripple and noise voltage.

Output in buffer mode:
The output voltage is fully regulated in buffer mode.
The unit switches into buffer mode, when the input voltage falls below the transfer threshold input voltage level, The
buffer voltage is slightly lower than this threshold input voltage. The unit switches back to normal mode, as soon as
the input voltage exceeds the transfer threshold voltage, which is specified in the input section.
