12V 12A SLA VRLA GEL AGM battery charger

Input:                                         100-240Vac 50/60Hz or 120V/230Vac 50/60Hz  
Output:                                       12V 12A
Charging mode:                            CC-CV-CV, 3 stage
Protection:                                   Short circuit, reverse, over-voltage, over-current
Safety Standard:                           Meet EN60335/EN61000

Data:

a. The charger integrates power factor correction (PFC), it can avoid the impact of high current and can't produce pollution  on the grid. 
b. Efficiency > 87% , Power Factor >0.97 for charger with 120V-240V input, or >0.7 for charger with 120V/230V input. 
c. With MCU controller, CC+CV(H)+CV(L) 3-stages charge method.

Protection: 
1. The charger's internal relay makes  the output voltage is less than 5.5V with no-load, when the output is connected to  a battery, the output voltage of charger is normal.
2. Short circuit protection: when the output of charger is shorted , the charger will close output automatically without any damage.
3. Reverse polarity protection: when the output is connected to a battery reversely, the charger will close output automatically without any damage.
4. Overheating protection: the internal temperature exceeds 80 ℃, the charger will close output automatically.
