VOLTAGE SENSING SPLIT CHARGE DEVICE
How It Works
When the engine is running, the Charge Guard senses the voltage and allows the charge through to the auxiliary battery.
When the engine is switched off, the Charge Guard monitors the voltage from the starting battery into the unit. When the voltage drops to 25.4V the unit will separate and isolate both batteries.
This means that equipment powered form auxiliary batteries cannot drain the starting battery.
Why You Need One
With today’s engine management systems and “intelligent” alternators you cannot use the charging light on the dash as a switch, also you cannot jump start most new vehicles without the danger of damaging the engine ECU.
This unit then becomes cost-effective.
Who Uses Them
Emergency vehicles where battery drain is a problem. Utility and council vehicles where multiple beacons/work lamps or power tools are being charged. The unit also has a one minute timer built in to eliminate damaging relay chatter caused by a flat auxiliary battery putting too much strain on the unit.
