12V-40A Low Battery Cut Out
When the battery voltage reaches 12.8V, the LBCO engages (it reverts to its original state) connecting the load to the battery, and the LBCO’s alert light switches off. When the voltage falls bellow 11V for 3 to 6 seconds, the LBCO automatically detects this and switches off the essential circuit load. This system eliminates the possibility of draining the battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.
Note: Specifications subject to change without notice.
