Product Advantage:

1)Dual-color LED indicator: Red means Charing, Green means full charged. With 3 years warranty.

2)Constant current, constant pressure dual scheme design, perfectly conform to the lithium battery charging characteristics.
3)The two-way average flow scheme is used, when one of them is damaged, only the charging current is reduced by half, and it can be used.

4)The charging time is adjustable, with LED indication, precision voltage, and current detection, effectively preventing overcharge and completely eliminating the charge of discontent and so on.

5)The input and output lines use high-quality wires, corrosion resistance, and no cracking.

6)The shell is PC industrial raw material, fire retardant and flame retardant, temperature resistance 75 C.

7)With output short circuit protection, even if the output short circuit will not damage the power supply, when the output short circuit release, the power supply is still normal output.

8)It has the function of soft start, can withstand frequent switch start, will not cause damage to the power supply.

9)The enclosure with a fixed installation hole, with a terminal, the input and output connection is extremely simple, no need to use a soldering iron.

10)The DC current is precise IC control, nonsingle triode constant current. Each cycle is monitored and the current limiting circuit is designed to prevent charge current from being too high, protect battery and extend battery life.

11)Built-in EMI filter device, anti lightning, surge voltage design.

12)Capacitance: capacitance is -40 C-105 C and C long life. The main products of international Dachang are ruby, black diamond, TOCON, YALECON and so on. Transistor: mainly used Silan, SILAN, ST, Fairchild.

Main parts:

   The case is made of aluminum alloy, which has good heat dissipation. The product has four built-in electric fans, forming a double convection system. Four sets of circuits are connected in parallel, one of which is damaged, and the product can continue to work, increasing the service life of the product.

 1) Input and output filter electrolytic capacitor use withstand temperatures -40 to +105?, with Low Impedance, High reliability, Long useful life, High ripple capability, etc features.

2)  Input Bridge KBP406 rectifiers Can withstand average Forward Rectified Current 4A, peak forward surge current 130A, Blocking Voltage 600VDC

3) The main power transformer adopts EC40core, PC40 material, High efficiency, low iron loss, Enough power capacity, Have sufficient power margin.

4) Using aluminum heat sink, Good thermal design, can better cool the power device, Consistent with the principle of hot air flow, extend the service life.

PCB Parts:

      Using SMD components, automated mass production by machine, Reduce manual errors, improve product quality.  Voltage conversion parts, With Cycle-by-Cycle Current Limiting, soft start function, with ESD Protection. The charge control circuit, Using precision voltage comparator, Precise control of the charging voltage and current, With overcharge protection, overcurrent protection, as well as output short circuit protection.

How to use:

1. Should be checked before using the battery charger is consistent with the type of charger model is correct. If the model is not matched, charging may be abnormal and the battery may be seriously damaged.

2. Should be properly connected battery Do not reverse polarity! (Red + Black- or Brown- Blue + or Red + Blue -).

3. Then the AC plug in the AC outlet, then the charger starts to charge the battery, charging status LED color light displayed by the top of the charger.(The indicator of LED: red is charging, green is charge finished or prepare to charge)If the green light is always on, check that the charging cable is firmly connected to the battery.

4. Full of voltage, first unplug the charger's power plug, then unplug the battery plug
