Chargery C4012B charger uses advanced Synchronous buck-boost DC/DC converter technology, high power, high current and high-performance power conversion circuit. The maximum charge power up to 40A 1500W at AC input, and 20A 500W at DC input, the maximum charge/discharge current is up to 40A. The charger can charge up to 12S LiPo, Lilo, LiTo, LiFe, with maximum 1.2A balance current, adopts unique balance circuit resume all cells voltage as fast as possible. 

Features

1. Unique charge architecture realized better transient response to any changes of voltage on input and output.

2. The charger use advanced ADC measurement technology, high accuracy, high voltage and high current detection circuit. The maximum voltage measurements tolerance is within 5mV at up to 12S LiPo battery.

3. The charger adopts advance balance circuit and Algorithm, constant 1.2A per cell balance current is very useful for large capacity battery pack, the feature can resume all cell voltage balance status at the shortest time. 

4. Maximal 100W discharge power need not any external load.

5. Charger internal temperature protection. When the internal temperature exceeds the setup temperature, the output power is automatically decreased; and the charger will stop working when temperature exceeds the shut-down temperature.

6. TFT LCD screen provides rich information including current, voltage, power, capacity, time, working status and temperature and so on.

7. The charger features a maximal safety protection,  

• Reversed polarity protection on input and output  
• Anti-spark on input and output even connect to 50V battery.  
• Wrong battery connection protection when multi battery pack connected in series on adapter board. 
• Charge time, charge capacity and battery temperature protection. 
• Over temperature protection during charge at DC input and at AC input 
• Over temperature protection during discharge 
• Over temperature protection during balance 
• Short-circuit protection on output, safer and more reliable.

8. Supports upgrading the firmware program by USB port. 

9. Active PFC: smaller AC input current less interference, and Conform to European Commission Regulation no 278/2009 and Energy Star Version 2.0

10. AC 90-265V worldwide operation: need not any alternative switcher, worldwide safe operation.

11. Low power consumption (less than 1W) when AC input and don’t conduct any program

12. Up to 94% of convert efficiency when AC input and 96% when DC input. 

13. As Power supply output voltage can be adjusted from 5V to 50V, and output current can be adjusted form 5A to 40A

14. 2 Intelligent cooling fans turned on upon the temperature automatically 

15. ZVS/ZCS and Synchronous Rectification assure the highest efficiency.
