Product description
The Battery pack for USV power adaptors consists of two sealed, maintenance-
free lead-acid batteries. They serve as backup batteries for an uninterruptible
power supply (1518 USV).
If the mains input voltage fails or drops below around 90 V AC, the connected DC
load of the uninterruptible power supply of the two batteries continues to be
supplied without interruption by two batteries.
The bridging time depends on the connected load and the batteries' state of
health.
