7. Method of Operation
In the event of a power failure at the output, the QUINT-DC-UPS supplies all connected devices with a 24 V DC
voltage without interruption at a load current up to 40 A. When the 24 V supply voltage is applied, the connected
battery module is charged. In the event of a supply voltage failure, the battery module is connected to the output,
and the stored power ensures that all connected devices continue to operate without interruption. The professional
signaling via function LEDs and
fl
oating PDT contacts enables reliable evaluation of all the main operating states.
7.1. Output Voltage
In normal operation, the QUINT-DC-UPS output voltage corresponds to the usual supply voltage. If the supply
voltage drops more than 1 V in the space of 0.1 seconds or falls below the minimum threshold of 22 V, the device
switches to buffer mode.
If the output voltage drops below 20.4 V in buffer mode, this is indicated by the Alarm indicator.
If the output voltage drops to 19.2 V because the battery module is
fl
at, the device is shut down completely. When
the supply voltage is reapplied, the device automatically switches on again. The device is electronically
short-circuit-proof and idling-proof.
7.2. Signaling
Three
fl
oating PDT contacts and three indicators are provided for function monitoring.

7.3. Temperature Response
The charging rate of the connected battery module depends on the temperature.
7.4. Testing the Battery Module
A quality test is carried out on the battery module once a week and its presence is veri
fi
ed every minute.
A negative test result is indicated by the Alarm indicator.
