12V 10A intelligent automatic quick battery charger (QW-B10A)QUEENSWING carries a range of high-quality battery chargers for off-grid, battery backup, car battery or just about any other application. Today's advanced battery chargers work with a wide range of battery technologies (lead-acid, AGM, gel) and include built-in safety and protection features to keep your system reliably operating for years.
Do I need a battery charger?
Most off-grid systems rely on a backup power source when the sun and wind is not adequate. Almost all of our off-grid customers are using solar power with a generator backup. A generator ties into an off-grid system through a battery charger.
Larger off-grid systems will typically use an inverter/charger which includes a high quality battery charger integrated into the inverter. An inverter/charger can eliminate the need for a separate battery charger. However it can still be useful to add another battery charger as a backup, or when using a modified sinewave generator with sensitive electronics.
Battery chargers are necessary when your off-grid inverter does not include a built-in charger (such as QUEENSWING's high quality sinewave inverters without charger.)
The brief instruction:
1. The QW series lead acid battery charger is professional designed according to the power battery of electric vehicles equipment.
2. It use the advanced soft switch technology, with small size, convenientinst allation, high conversion efficiency, running fully loaded for a long time, stable output current, large capacity, high reliability, long life features etc.
3. With short circuited protect, low voltage protection, overheated protection function.
4. The long delay digital counter can ensure the battery form the constant voltage to the float charge reliably every time, avoid the lost control of battery heat caused by the high temperature.
5. Make the damage of battery drop to the loest caused by the dehydration and the polar plate vulcanize which are the two general problems of charger, MAD.Technical Parameter:| Model No. | QW-B10A |

Protection:
Over-heat protection: When the temperature of charger shell over 85ºC, the charing current auto reduced to half of the orifinal current, when the temp. over 105ºC, the charger protective turn off, this moment no current input, auto recover charge when the temp. fall to about 80ºC.
Short-circuit protection: When the charger input happen to short-circuit, the charger input auto turn off the charge will charge again after restart.
Low-pressure protect: When the battery simple lattice lower than 1.4V, the charger protective turn off or unable to start to avoid the damage equipment when the battery doesn't match the charger nominal voltage.
Three-stage charging:
Constant current: When the voltage of the battery is lower than the value set by the charger, the charger will work under the constant current mode and supply the constant current for the battery.
Constant voltage: Using the pulse width modulation (PWM) tech to control the charging current and output voltage of the charger which ensure the battery is charged fully and avoid over charged.
Floating charge mode: When the voltage of the battery is closing the value of the constant voltage mode, and the current cut down to the given current gradually, that is meant the battery power is full, then the pilot lam will turn green and the fan will stop working. The charger will turn the mode into floating charge mode automatically. At this moment, the battery can be stopped charge or kept on flating charge.
