Auto Charge 20

The Auto Charge 20 is a fully automatic, triple-output battery charger designed to independently charge and maintain three separate 12-volt battery banks. This versatile unit is specifically engineered for use in fire apparatus, rescue vehicles, ambulances, and other emergency or specialty vehicles where multiple battery systems are common. The Auto Charge 20 uses three independent sensing and charging circuits to provide each battery bank with charging current based on its individual condition and electrical demands, ensuring that each battery receives the appropriate level of care without interference from others.

One of the key advantages of the Auto Charge ight is its ability to monitor and charge each battery independently. This means that parasitic loads connected to one battery bank do not negatively impact the charging performance of the other batteries. Although the charger provides a maximum total output of 20 amps, any individual battery bank can receive up to the full 20-amp output when the other banks do not require charging. This intelligent distribution of available charging power helps optimize battery recovery in vehicles with different electrical loads across multiple battery banks, ensuring that each system is maintained effectively.

The Auto Charge 20 features a heavy-duty aluminum enclosure designed to withstand the demanding conditions of emergency vehicle environments. The charger includes a protective front panel plate and integrated wire strain relief, making it suitable for both vehicle-mounted and wall-mounted installations. These design elements ensure durability and reliability in challenging operational settings. Additionally, the unit provides convenient monitoring through a front-panel ammeter that displays the total charger output current, while optional remote indicators offer further flexibility in tracking battery charging status from a distance.
