A stored energy time of 5 to 10 ms is guaranteed in the event of a power failure.

The stored energy time is dependent on the input voltage and the load.

A stored energy time of 20 to 30 ms is guaranteed in the event of a power failure.

The stored energy time is not dependent on the input voltage and the load.
