PEAK DBI 12 OR 24 VOLT LOW VOLTAGE DISCONNECT 

 

These units are manufactured in South Africa and have an exemplary track record.

 

Product Description

Install this device between a battery and its load and it will automatically protect the battery from excessive discharge by disconnecting the load. A battery, especially a non-deep cycle one, which is run until it is empty or nearly empty of charge will have its operational lifetime reduced and future ability to hold its full rated charge impaired.

 

Or in a direct solar application install the LVD between a solar module and a load to prevent the load from running underpowered when there is not enough sun on the module, as this could damage some motors.

 

The user can program any of 20 disconnect and 20 reconnect values via an external pushbutton. 

The unit corrects any illegal/faulty programming and shows it. 

The unit comes preprogrammed with recommended popular default values. These default values are permanently stored in the firmware and can easily be restored by the user. 

The programming procedures, reconnect voltage table, disconnect voltage table and wiring diagram are described/shown in a comprehensive user instruction manual.

 

To increase load handling capabilities add an external heavy duty contactor/relay. The cutout will then drive this external contactor/relay which in turn will switch the load.
