Voltage guard

The Voltage Guard protects batteries from deep discharge by disconnecting loads when a preset low voltage level is reached. This is critical to ensuring a long battery lifetime. The Voltage Guard also provides fixed point over-voltage protection.

Features:

The status of the Voltage Guard is indicated through a multi-colour LED light. When the battery voltage is within the operating range the light will be green and the output enabled.

When the voltage is lower than the set point the LED will turn orange. After 30 seconds the output will be switched off and the LED will turn red. A long audible tone will sound three times to indicate the error.

The output will be switched off if the battery voltage rises above 15V or 30V. The LED will then be red. A medium duration audible tone will sound three times to indicate the error.

If the Voltage Guard is overloaded for a long period of time the output will also be disabled. A short audible tone will sound three times to indicate the error.
