Description VOIP mit Notenergie. Funktionsweise: Das 12 Volt Netzgerät des abgebildeten Routers wird durch den angeschalteten Akku im laufenden Betrieb gepuffert. Bei einem Stromausfall erfolgt eine 12 Volt Speisung unterbrechungsfrei aus dem Akku welcher ca für 30 Stunden VOIP Gesprächsdauer ausreichend Energie bereitstellt. Bei Rückkehr der Energieversorgung genügt erfahrungsgemäß das elektronisch geregelte Original Router Ladegerät um eine Überlastung durch den entladeten Akku zu vermeiden.
