The Auto Charge 20/20 is an intergrated charger with Battery Saver Low Ripple. Designed for installation on vehicles with a single battery system. The charger completely operates automatically and stops charging the batteries when they are fully charged. There is no trickle charge and therefore no danger of overcharging and water boil-off.
The Battery Saver output provides uninterrupted power to accessory loads whenever the vehicle is connected to AC power. This complete package simplifes installation and improves system relialility due to parasitic loads. These loads will be connected to the battery when the vehicle is in use but are removed automatically when shore power is supplied and are then powered by the Battery Saver.
Ammeters are provided to indicate Charger and Battery Saver output currents.
The charger is also ruggedized to withstand the shock and vibration encountered by vehicle mounted equipment.
