Operation

Backup Function
(Backup status indication, Operation mode output)
S8T-DCBU-01 detects output voltage drop of S8TS-06024@ to
switch to backup operation.

Note: 1. If this state occurs, a probable cause is an S8TS-06024@
overload or it is out of order. Immediately eliminate the
cause of the trouble.
2. If switching between backup operation and Normal opera-
tion is repeated, the output voltage changes accordingly.
3. The contact capacity of the relay is 24 VDC 0.1A.
4. Upon a steep load fluctuation, the output voltage of S8TS-
06024@ drops to switch to backup operation.
5. The maximum inrush current specified below (on assump-
tion with a 56000 µ F capacitive load) flows when backup op-
eration starts.

Note: The battery takes the time specified above to be charged.
If power failure occurs at time shorter than the necessary
charging time, backup operation may not continue for the nec-
essary time.
Output Voltage Adjustment for
S8TS-06024@
The DC backup block detects output voltage drop of connected
S8TS-06024@ to switch to backup operation.
Do not set the output voltage of S8TS-06024@ to lower than the fac-
tory shipment setting because, even though the output voltage of
S8TS-06024@ is adjustable with Output voltage adjustor. Otherwise,
it may operate in the backup operation mode.
