Battery Guard are the ideal solution for operators and installers, when batteries need to be protected from heavy discharge due to additional loads being fitted.

The Battery Guard is a Microprocessor controlled, solid state, switch (FET). The battery voltage is constantly measured, and an alarm output will be activated whenthe battery voltage is too low for 15 seconds.

This alarm output can be connected to a buzzer or small lamp. If there are no changes within the next minute the Battery Guard will disconnect.

When the battery voltage is much too high the consumers will be disconnected immediately and the alarm (contact) will be activated alternating on and off.
