Note
Restriction when using a SITOP BUF8600 4 s/40 A buffer module in a 40 A- power supply
system
When using a SITOP BUF8600 4 s/40 A buffer module in a 40 A power supply system, the
150 % overload capability for 5 s/min (Extra Power) and 300 % for 25 ms (Power Boost) are
not supported.
The buffer mode is immediately exited if a system overload > 100 % occurs during buffering.
When using a buffer module with double-layer capacitors, the following additional functions
are available:
Brief interruption of the voltage at output 1
If a PC is operated on the PSU8600 power supply system, when the power fails, then this
must be run down in plenty of time before the buffer time expires in order to avoid data being
lost. If the supply voltage returns after the shutdown has already started, the buffer mode is
exited and the power supply resumes normal operation. However, the PC is run down
completely. If the PC does not have an on/off switch, then it can only be rebooted by
switching off the power supply and switching it on again.
To activate the brief interruption of the voltage at output 1 when the supply voltage returns,
for a buffer module with double-layer capacitors, the "Enable short-time interruption output 1"
function is used. However, the selection and parameterization is only possible via the
configuration (STEP 7, OPC UA Server, web server).
