![]() |
DANGER System voltage can only be switched on or off by plugging in or unplugging the power plug. If using a USVF, deactivate battery mode first. |
Capacities and Bridging Times for Uninterruptible Power Supplies
The battery bridging times during power outages are determined under the following conditions for the USVC in OfficeCom and the USVF in OfficePoint:
![]() |
The power supply units in the system are operating at 60% of capacity. |
![]() |
The battery ambient temperature is +20 degrees Celsius. |
![]() |
The cut-off voltage is 1.7 volts per cell. |
![]() |
The batteries are fully charged at the beginning of the power outage. |
The following reference values apply to the bridging times, based on the conditions listed above:
Voltages per Battery Cell (example: Yuasa)
Charging current with current limiting: |
2.4 V |
Charging current without current limiting |
2.275 V |
Discharging current |
1.7 V |
The battery cell voltage is 2.0 V, and the available capacity sampled between 2.3V and 1.7V.
![]() |
Follow the manufacturer's instructions for charging and discharging the batteries. |
