Time Charts
Startup
Note:
Backup operation is not possible during the period (7 seconds (typical)) that the
battery status output relay is LOW after the S8T-DCBU-01 is started up.
Power Failure (When the Battery Voltage does
not Reach the BAT LOW Voltage)
Note:
Backup operation is continued for seven seconds after the power is restored from
a power failure.
Power Failure (When the Battery Voltage
Reaches the BAT LOW Voltage)
Note:
When the battery voltage falls below 22.5 V (typical), the status of the battery
status output relay changes to LOW.
Power Failure (When the Battery Voltage
Reaches the Overdischarge Protection Voltage)
Note:
When the battery voltage falls below 22.5 V (typical), the status of the battery
status output relay changes to LOW, when the battery voltage falls below 18.5 V
(typical), backup operation is stopped.

Backup Time (Reference Value)
Note:
1.
Backup time conditions
• Ambient temperature: 25ºC
• Battery: New product fully charged to 27.4 V
• Length of wire between S8T-DCBU-01 and battery: 1.5 m
2.
The backup time changes depending on the capacity of connected equipment, ambient temperature, and battery service life.
