All parameters are specified at 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.
It is assumed that the input power source can deliver a sufficient output current.

7. Output in Buer Mode
If the input voltage falls below a certain value (transfer threshold level), the DC-UPS starts buering without any
interruption or voltage dips. Buering is possible even if the battery is not fully charged.
nom. DC 24V Output voltage is stabilized and independent from
battery voltage
Output voltage in buer mode
22.45V ±1%, at no load,
22.25V ±1%, at 10A output current
typ. 80mV higher than the output voltage in buer mode Transfer threshold for buering
Ripple and noise voltage max. 20mVpp 20Hz to 20MHz, 50Ohm
Output current nom. 10A Continuously allowed
15A < 5s with full output voltage *)
Short-circuit current min. 17.9A Load impedance 100mOhm **)
max. 21A Load impedance 100mOhm **)
*) If the output current is in the range between 10A and 15A for longer than 5s, a hardware controlled reduction of the
maximal output current to 10A occurs. If the 10A are not sucient to maintain the 24V, buering stops after another 5s.
Buering is possible again as soon as the input voltage recovers.
**) If the nominal output voltage cannot be maintained in buer mode, the DC-UPS switches o after 5s to save battery
capacity.
