Protection of circuit from over current by Fuse
Both of Ni-Cd and Ni-MH batteries from 7.2V to 14.4V
can be charged with DC1413 (LG125), in shorter time
comparing with the existing charger DC1411.
Its maintenance (trickle) charging system keep the full charged
condition, even if the battery is left in this charger after
finish of charging process.

Features and benefits P 2 / 4
Ideal charging system in this class with the following installations
* Controlling by micro computer : The installed micro computer perceives the full charged condition, and
control the optimum way to stop the charging process, from the followings.
* Trickle charging mode : Continue to produce very small charging current (approx. 40mA) for full charged
battery left in charger.
* Constant output current (charging current)
: By keeping the output current (Ampere) in the constant level, it is possible to stop
the charging process with perceiving the battery's voltage drop exactly.
Namely it is possible to perceive the full charged condition by the above
"Minus delta V system ".
A) Minus delta V system : Stop the charging process with perceiving the battery's voltage drop.
B) Delta T system : Stop the charging process with perceiving the change of battery's temperature.
( This system is applied to only the charger of 4 terminal-type.)
C) T system : Stop the charging process with perceiving the battery's temperature which is
input in the micro computer in advance. For instance the charging process is to
be stopped at 45 ° C for 1.3Ah battery, and at 60 ° C for 1.7 - 2.2Ah battery.
D) Timer system : Stop the charging process in 150 minutes after starting the charge, if the full
charged condition would not be perceiving with any of the above 3 systems.

* Current transforming system : The built-in "High-Frequency Tranceformer"supplys the charging current as follows.
1. Convert alternative current into direct current.
2. Re-convert the above direct current into alternative current, however, high
frequency of approx. 150 - 160 kHz in this stage.
3. Reduce the voltage to the battery's voltage.
The feature of "High-Frequency Tranceformer" is light and compact comparing
with the existing trance.

<1> The circuit board can not be repaired, because the circuit itself are molded on the board .
It has to be replaced as a set with new one.
<2> In case of damaged varistor or fuse, they can be repaired according to the following procedure without
replacing the circuit board.
(1) How to find broken varistor
a. In case that the surface of varistor (ref. to the following illustration) has broken or has become black, and
fuse has been cut, the varistor has been damaged.
b. Varistor can be damaged easily, if the charger is plugged in a double voltage of the rating one.
c. It is considered that the varistor has been broken for other reasons, if the fuse is broken while the surface
of varistor is not damaged. In this case circuit board has to be replaced.

(2) Replacing damaged varistor
a. Varistor is assembled on circuit board with solder. Remove it from circuit board
with soldering iron.
(3) Replacing damaged fuse
a. Fuse is assembled on circuit board with solder. Remove it from circuit board with soldering iron.
b. Assemble new fuse to the circuit board by soldering.
c. Cut the surplus of fuse's wire with nipper.
b. Assemble new varistor to the circuit board by soldering.
c. Cut the surplus of varistor's wire with nipper.
