●
Buffering allowed
Select between buffers with the specified values or passive measurement of the power
supply by the UPS.
●
Connection threshold
If the connection threshold value is undershot, the UPS starts buffering. If the value of the
connection threshold is reached or undershot again later, the UPS stops buffering.
●
Buffer time
The time to be buffered by the UPS. The "Buffering allowed" parameter is used to specify
whether buffering should be performed.
●
Additional buffer time after PC shutdown
Time, to be buffered by the UPS1600 after the PC has been shut down.
●
Stop buffering voltage
The voltage at which battery discharge is terminated.
