Dipper Star Aluminum Shell 12V20A Lithium Battery Charger

I. Basic Parameters and Functions 　· Circuit structure:Dual-tube resonant LLC charger 　· Input power: Standard 220V/50Hz household alternating current. 　· Charging Efficiency: Normal charging efficiency is approximately 94%. II. Core Protection Functions 1. Short-circuit Protection: When an accidental short circuit occurs in the output circuit, the charger will automatically cut off the output to prevent damage to the device and reduce the risk of fire. 2. Smart Timing Protection: · Efficient Charging Zone: Continuous charging should not exceed 8 hours. · High-Voltage Charging Zone: Continuous charging should not surpass 3 hours. · Total Charging Duration: The combined time for both the efficient and high-voltage zones must remain under 10.5 hours. 3. Reverse-Connection Protection: If the battery is connected backward, the output current will be strictly limited to below 5mA, safeguarding against damage; once corrected, the charger can resume normal operation. 4. Delayed Automatic Cut-off: After charging is complete, the system will automatically switch to trickle charging or completely stop the output (current < 5mA), effectively preventing overcharging of the battery. 5. Pre-Charge Activation (Optional): By delivering intermittent output voltage, this feature helps wake up lithium batteries that are currently in undervoltage protection mode, enabling them to enter normal charging status.
