INPUT:  12VDC   12VDC   24VDC   or   48VDC

DISCONNECT:  10.4VDC  10.4VDC  21VDC  42VDC

CONNECT:  12.2VDC  12.2VDC  24.5VDC  49VDC

ADJUSTMENT RANGE:  9-15VDC  9-15VDC  18-30VDC  38-60VDC

Discharging batteries beyond a critical low voltage can damage the batteries and/or load, and require a longer recharge interval. A low voltage disconnect prevents this condition. The LVD contains a sense and control circuit housed in a compact, rugged, vinyl-clad aluminum case. It is installed in-line between the battery and the load. The unit continually monitors battery voltage and if it falls below a preset voltage threshold, the load is automatically disconnected. When batteries are recharged past another pre-set voltage the load is reconnected. Connect and disconnect points are user adjustable.
