PD9100L Series 12V Lithium Ion Battery Converter/Chargers provide a Constant Current/Constant Voltage (CC/CV) charge profile as recommended by lithium battery manufacturers. PD9100L Series units can be connected both in parallel and in series. Reverse battery protection prevents charger damage if the battery connections are accidentally reversed. Filtered DC power ensures proper lithium Battery Management System (BMS) operation. Electronic Current Limiting automatically reduced output voltage to prevent overheating and possible damage. High and Low Voltage Protection prevents charger damage from AC input voltage fluctuations. Automatic Thermal Protection reduces charger output to safe levels if unit temperature exceeds safe levels pre-set limits and protects charger damage due to excessive heat. An intelligent cooling fan operates only under high load conditions. Input Voltage: 105-130 VAC 50/60 Hz 725 Watts. Output Voltage: 14. 6 VDC 45 Amps.
