Programmable Battery Guard

The programmable battery guard (BG) prevents the excessive discharge of the battery (which would damage the battery) and protects electronic appliances against over voltage. The battery guard is automatic detectable; that means the BG is automatically selecting the correct input voltage (12 or 24Vdc).

Fully Programmable
The battery guard can be set to engage/disengage at several different voltages. The BG is microprocessor controlled and has 10 different selectable programs.

Overvoltage Protection
To prevent damage to your sensitive loads due to over voltage, the load is disconnected whenever the DC-voltage exceeds 16V or 32V.

Ignition Proof
No relay but MOSFET switches, and therefore no sparks.

Alarm Output
The alarm output is activated if the battery drops below the present disconnect level for more than 12 seconds. Starting the engine or battery charger will therefore not activate the alarm. The alarm output is an open collector output to the negative (minus) rail, max current 500mA. The alarm is typically used to activate a buzzer and/or lamp.

Load Disconnect
Only 1 minute after the alarm has been activated the load will be disconnected, but if the battery voltage increases to the connect threshold within this minute (after the engine or battery charger has been started for example) the load will not be disconnected.
