3000 Watt Rackmount DC-AC Inverter
This power inverter provides seamless back-up power for AC powered communications equipment from the site’s 48V DC battery system. A fast-acting transfer switch ensures voice and data transmissions remain uninterrupted in the event of a power grid failure or if the site utility power is disconnected for maintenance and upgrade purposes. Built in a 2RU case for 19″ rack installations.
