SITOP UPS1600 / UPS1100

●
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.
●
Additional buffer time after PC shutdown
Time during which the system should be buffered by the SITOP UPS1600 after the PC
was shut down.
●
Load current, which is expected at the device output during buffer operation. Please
adjust the correct application load current required. For current settings between 0 A and
rated current, the display in the diagram "Remaining buffer time" is adapted.
If a value of 0 A is entered, then for this parameter, the average value of the actual load
current measured at the output over the last 10 min is assumed. The value of this
parameter is used when calculating the remaining buffer time. The entered value may not
exceed the rated device current.
Note
From the instant in time when the SITOP
UPS1600 is switched over into the
buffer mode,
to determine the expected buffer time, instead of the expected buffer current, the actually
measured buffer current is used.
●
The voltage at which battery discharge is terminated. The stop buffering voltage defined
for this type is always used for a coded battery (UPS1100).
●
If the value is set to "Yes" then the output voltage is interrupted after the selected buffer
time expires if, in the meantime, the input voltage returns. This option is useful, when, for
example, computer networks are protected by the UPS that can be activated by a reset
when the power supply is restored. For buffer time "MAX", the output voltage is not
interrupted.
●
Here, you define the interrupt duration.
●
The time interval between battery tests can be set using the parameter.
