The NetWave NWKBB200 DC-Battery Power Solution provides consistent power for your devices in locations where power is on a timer or they have frequent blackouts or brownouts. The NWKBB200 supports AC input ranging from 110 to 277 VAC, and can also support higher voltages using a Step Down Transformer. The intelligent controller distributes power to the load and batteries when AC power is available and instantly switches over to DC output only when AC power is lost. The kit includes valve-regulated lead-acid batteries, outdoor enclosure, mounting hardware and Smart DC-Battery Power Controller. The aluminum outdoor enclosure has two 180° door hinges and a pad lockable latch for security. The enclosure has built in mounting brackets that support pole and wall mounting.
