Battery Charger,battery chargers,LEAD ACID BATTERY CHARGER

1.Main product specification

Max. output power	Input voltage	Output voltage	Output current range	Combined regulation
3000W	200-240Vac	+88.2+/-0.2Vdc	30+/-1.0A	+/-0.2V

2.Environmental condition

No.	Item	Technical specification	Remark
1	Humidity	5~95%	With package
2	Altitude	≤3000m	Work normally
3	Cooling	The power supply is cooled	Working under full load

3.Electrical characteristics

4.1 Input characteristic

No.	Item	Technical specification	Remark
1	Rated input voltage	240Vac
2	Input voltage range	200~264Vac
3	AC input voltage frequency	47~63Hz

4.2 Output characteristic

No.	Item	Technical specification	Remark
1	Fast charge voltage	88.2+/-0.2Vdc
2	Floating voltage	82.8Vdc
3	Constant current	30A
4	Switch current	6.0A
5	Power efficiency	≥90%	Vin=220Vac, rated load

4.3 Protection characteristics

No.	Item	Technical specification	Remark
1	Over voltage protection		Lock out
2	Software over voltage protection	The charger software limits the maximum output voltage to a level suitable for the connected battery system
3	Thermal protection	An internal temperature monitor reduce charger output power in extreme operational temperature to prevent damage
4	Current limiting protection	30A	At CC mode
5	Short circuit protection	Short circuit protection should be automatically recovery after remove the condition
6	Reverse polarity protection	When output wires are reversely connected to the battery the charger will not operate and will work normally when DC wires are correctly connected.
7	Fan cooling	The fan is controlled by a temperature sensor. After charger works , the fan will run for 2min or so ( even several seconds); if the charger temperature is below 30~45 ℃, the fan will stop; if the charger temperature rise, the fan will run again;

4.4 Charging indicator

No.	Item	Status	Remark
1	Power on	LED1: red
