The brief instruction
The MA series lead-battery charger is professional designed according to the power battery of electric vehicles epuipment. It use the advanced soft switch technology,with small size,easy to installable, high conversion efficiency, running fully loaded for a long time,stable output current,large capacity,high reliability,long life features etc. With short-circuited protect,low-voltage protect,overheated protect function. The long delay digital counter can ensure the battery from the constant voltage to the float charge reliably every time. Avoid the lost control of battery heat caused by the the hight temperature. Let the damage of battery drop to the lowest caused by the dehydration and the polar plate vulcanize which are the two general problems of charger.
Operating mode of four-step charger
Pre-charge mode:In order to protect the battery and extend its life,the battery's internal resistance is too large or voltage is too low bacause the discharged time is too long or it is not used for a long time, the charger will supply low output current for the battery automatically. When voltage of the battery rises to the given voltage value, the charge mode will turn to constant current charge mode automatically.
Constant current mode:The charger supply constant charge current for the battery.
Constant voltage mode: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 means the battery power is full,then the pilot lamp 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 floating charge.
1.RED-charge LED:The red light turn on indicated that charging for the battery by rated current.
2.Green-ok LED:The green light turn on indicates that the charger is in the float mode for charging. This moment added the final 95%~100% electricity. Leaving the battery connected to the charger for two or three hours, that will make the battery storage for the best function.
1.Check the battery rated voltage whether match the charger output voltage or not;
2.Connect the charger and the battery as the right requestion;
3.Check the city power voltage whether match the charger rated input voltage or not;
4.Connect the city power,then check the indicator turn on or not,the fan work or not;
5.If the indicator light off,please turn off the city power at once,ane check city pwer and storage battery and all the line;
6.After charge the battery fully,please turn off the city power first,then turn off the battery connect wier.
