The Go Power! 10 Amp Smart Charger is designed specifically to extend the life of deep-cycle battery banks. With a unique microprocessor controlled electronic design, the Go Power! Smart Charger offers multi-stage charging to accurately recharge and maintain your battery banks without electrolyte loss. The Smart Charger has a high frequency switching mode and is equipped with a micro-controller and a PFC circuit. This design allows this Battery Charger to perform with intelligent battery management and reliable operation. The Smart Charger features a three stage charging process that provides more sophisticated and faster charging than conventional transformer type chargers. The charging stages are: Bulk Stage: Constant current charging at a high voltage level at maximum amperage Absorption Stage: Tapering current for the last 10-20% of charge Float Stage: Lower voltage float mode to prevent electrolyte loss It also features an LED display, reporting charging state, short circuit protection and over-temperature protection. The high efficiency electronic design makes the GPSC-12-10A the ideal choice for use with generators and for backup charger applications. Features: Advanced 8-bit microprocessor control circuit, reverse battery protected by fuse, ignition protection Output short circuit protection and overpower protection Switch mode technology Easy-to-read LED for system status Compact size and lightweight Power factor corrected to 0.98 = efficient charge
