Make your FTTH network more resilient!
How the battery works
During normal operation, the main adapter powers the connected devices and keeps the batteries inside the housing charged, providing a 30W backup power supply for 1 hour in case of a power outage. In addition, the FTTH Battery provides the appropriate voltage for the connected devices (5 V, 9 V, or 12 V), determined by a smart connector at the USB port, and supports up to 3 devices (e.g. gateway, Wi-Fi router, and telephone adapter simultaneously).
Warning functions
Another feature making our FTTH Battery 2 unique is the overload warning function. In case the connected devices require so much power that the promised 1-hour backup can no longer be guaranteed, a warning indication is issued via an LED. Furthermore, if batteries have aged and less than 1-hour backup duration can be expected at 30W, another LED will indicate the need for battery replacement, which can be done by the end user with just a few simple steps. (Please find the battery replacement instructions below.)
