Caution: Connect the battery positive and negative poles should never be reversed (red positive and black negative)
Using power supply model: (Emerson ) EMERSON server power supply installation central control modification. (Imported brand)
Input voltage: AC 100V ---250v
Input power: 675W up to 700W
Output voltage: DC constant voltage to meet 2.3V-15V (suitable for charging all batteries within the voltage range)
Output current: DC constant current to meet the 1-50A adjustable. (Only constant current and constant voltage can do the charger)
Protection mode: constant current output after a short circuit of the positive and negative poles. (Do not positive and negative short-circuit for a long time)
Appearance size: 24CM long * 8.5CM wide * 6.6CM high.
Weight: 1.5KG.
Standby power: about 11W.
Cooling mode: air-cooled (built-in cooling fan, with the temperature increases, the speed increases)
Accessories: with two positive and negative lines and copper nose, (power input line need to provide their own) output line using two 80A quality silicone wire.
Method of use.
Step 1: The charger first do not connect the battery, turn on the power, adjust the voltage knob to adjust the voltage, refer to the voltage display above the display, (four strings of lithium iron batteries 3.65v * 4 = 14.6 volts, three strings of polymer batteries 4.2v * 3 = 12.6V), adjust to the voltage you need.
Step 2: Adjust the current to the minimum, after connecting the battery, adjust the current from small to large, adjust to the current you need. (In the charging process, do not allow to adjust the voltage knob again, otherwise there will be overcharge or undercharge)
If the voltage is displayed, the voltage you set, the current becomes zero, it is already full.
Lead-acid batteries do not support high-current charging, to be charged with a current of 1/10 of the capacity. For example: 100AH with 10A charging, 150AH with 15A; and so on. The current can not be adjusted to too large, otherwise there will be damage to the battery, the time must meet 8-10 hours, the time is too fast, the current is too large, it will damage the battery. Lead-acid battery charging voltage at about 14 volts, different manufacturers of batteries, the voltage is slightly different, subject to the instructions on the battery label! You can also check Baidu! Individual reflect the shell charged numb hand situation: the power cord is a three-wire input, one of the ground wire, the above situation is your power ground is not connected or broken, connect the ground wire can be! No ground wire is not reversed, that is the reason for the dry ground shoe insulation. (Family refrigerators, washing machines, water heaters and other appliances do not ground wire will have this phenomenon, the basic common sense issues do not do much to explain, you can Baidu to understand the details!) On the output line temperature description: the output line is used 80A high-quality silicone wire, temperature resistance of 200 degrees, softness superb unconventional wire, the maximum current of 100A, the line temperature at about 50-60 degrees, the current temperature are within reasonable parameters.
