50 Amp Car Battery Charger PRV SC-50AMP Power Supply and Smart Automatic Maintainer The SC-50AMP Smart Charger is a modern and efficient 3-in-1 automotive battery charger and power supply unit designed to deliver ideal voltage to batteries while consistently preventing overcharges. This adjustable Power Supply unit can eliminate the need to run your car alternator and supply power to a 12v system without the use of any batteries. The PRV SC-50AMP can run your system just as a car alternator would. When installed in your show car, home system or test bench, it can plug into a standard wall outlet to power your 12v equipment. Built-in Multimeter Display: Voltage / Current / Average Amps per Hour Microprocessor Charging System (MCS) Smart Battery Charger: Its microprocessor controls current flow while batteries are charging, guaranteeing no overcharging, and always maintaining set voltage. Eliminate hours of charging on a large battery bank, where more batteries demand additional current to be able to charge faster. Constant 50A current and constant 14.4V voltage, very suitable for charging any AGM, GEL, lithium-ion or LiFePO4 automotive, marine and deep-cycle 12V batteries. Adjustable Power Supply (APS) Power on Demand: The SC-50AMP is not only a charger, but a real power supply able to deliver instant power to your system! Adjustable voltage and current controls help set the best performance according to the available power source. A great addition to your custom-sound-system loaded show car, the SC-50AMP lets you: Avoid idling your vehicle for hoursSave on gasPrevent unnecessary engine wearor even power your custom 12v home system without the use of batteries The SC-50Amp can supply power to a system, up to 1000-Watts, without the use of any batteries. Adding a 100Ah battery will allow you to power a system, up to 3500 Watts, for about 1 hour of play time before having to fully recharge the battery. The larger the battery bank, the longer you will be able to play or the more power on demand you will have access to for a short period of time. Fully Automatic Battery Maintainer (FABM) Charge Loop: When you reach 14.4v, the Maintainer mode will start. After 3 hours of charging at 14.4v, the voltage will drop to 13.8v, maintaining such voltage for up to 23 hours. A final equalization mode then brings voltage up to 14.4v for 1 hour. The FABM mode will keep the unit in an infinite loop on this cycle while plugged in, preventing overheating and permanent damage to batteries. Its adjustable amperage control gives you ultimate control when powering/charging your system, without the risk of tripping any breakers. Should the power outlet not be strong enough, you can adjust the amperage output on the power supply to match the circuit power grid that you are plugged into.
