Description of the buffer modules
A SITOP BUF8600 buffer module extends the buffer time for brief power failures. Up to two
buffer modules can be used for each basic unit. An LED signals the operating state of the
buffer module. For buffer modules with double layer capacitors, using a control contact,
buffer operation can be deactivated, and using two signaling contacts, information regarding
buffer readiness and buffer operation can be processed. The connection to the basic unit or
to the adjacent module is established using an integrated connecting plug.
For brief power failures, the energy stored in the buffer module supplies the power supply
system outputs without any interruption.
Buffer module versions
There are two BUF8600 buffer module versions available: Buffer modules with electrolytic
capacitors and buffer modules with double-layer capacitors.
