The powerful and compact battery pack with a capacity of 2.6 Ah at 37 VDC output voltage ensures uninterrupted operation of the door system. Up to 800 opening cycles or continuous opening over 24 hours are then possible with a full charge, depending on the door dimensions and the programmed settings.
The battery pack can be attached to the swing door operator DFA 127 or elegantly integrated into the extended operator variant in the kit version.
If the power failure lasts for a long time, the switched-off door system can be set to battery operation by means of remote control (wake-up mode). One impulse is enough and the drive control starts, opens the door, returns to idle mode and the door then closes again with spring force. The built-in buzzer optionally signals mains-independent battery operation.
