• Buffering permitted
When the connection threshold is fallen below, selects whether the system is buffered or
the output is shut down.
• Switch-in threshold
Setting the switch-in threshold.
• Buffer time
Length of time during which the system should be buffered by the SITOP UPS1600.
• Maximum buffer time
The setting means that buffering is realized for as long as possible. The device only shuts
down when the battery has discharged down to the defined stop buffering voltage. The
value entered for the "Buffer time" parameter is not relevant in this case.
• Discharge cut-off voltage
Voltage at which battery discharge is exited. For a system battery (SITOP BAT1600 or
SITOP UPS1100) the discharge cut-off voltage defined for this type is always used.
• Additional buffer time after PC shutdown
Time during which the system should be buffered by the SITOP UPS1600 after the PC was
shut down.
