12v/24v 5-30A battery charger 3 charging stages battery charger

3 charging stages battery charger over-charged &thermalprotection output short circuit protection reverse connect protection

This battery charger is specially designed for Lead Acid battery, with constant voltage, and constant current, trickle charge, over-charged and short circuit protection functions.

1.Applicable scope

1)  Suitable for charging all kinds of Lead-acid battery.

2)   Input working voltage:AC140-270V,Working frquency:47-63HZ

3)   Working environment: -40°C~+50°C <98%RH

2.Function characteristics

1)    constant-current charge

When the battery voltage is lower than the set point, battery charger will charge the battery at the max. constant current,this is called Quick Charge.

2)   constant-voltage charge

When the battery is almost been fully charged,the battery will limit the current automatically.

3)   Float charge

When the battery voltage reaches the setted float voltage(12V:13.5V,24V:27.5V),it will automatically switch to the float charge condition,and charge with the current0.1-0.3A.

4)  Stop charge

When the battery voltage reaches the fully charged point(12v:14v,24v:28v),it will cut-off and stop charging.
