Output in Buffer Mode

If the input voltage falls below a certain value (transfer threshold level), the
DC-UPS starts buffering without any interruption or voltage dips. Buffering is
possible even if the battery is not fully charged.

(1) If the output current is in the range 10 A...15 A for longer than 5 s, a hardware-controlled reduction of the maximal output current
to 10 A occurs. If the 10 A are not sufficient to maintain the 24V, buffering stops after another 5 s. The buffering is possible again as
soon as the input voltage recovers.
(2) If the nominal output voltage cannot be maintained in buffer mode, the DC-UPS switches off after 5 s to save battery capacity.
