Warning
1. The installation of this equipment must be carried out by professionals.
2. When installing and operating the Charger, please read the entire instruction
manual first.
3. Any maintenance and commissioning of the equipment must be familiar with all the
equipment, safety standards and precautions in advance, otherwise it may cause
personal injury or damage to related equipment.
4. This product is specially designed for charging lead-acid batteries. Because of the
output contains impulse components, it can not be directly used as a power supply
for electronic equipment without lead-acid batteries. Otherwise, it may cause
interference or even damage to electronic devices.
Be Care
1. Please pay attention to prevent water or other liquid from being sprinkled on this
charger.
2. When using this charger, we should pay attention to ventilation and heat
dissipation and keep away from high temperature and heat radiation.

Summary
The charger is specially designed for the lead-acid battery used in the engine. It
adopts the three-stage intelligent control mode of constant current fast charging,
current limiting and trickle floating charging. It can be charged for a long time without
damage to the battery. It can maintain the full state of the battery and ensure the
service life of the battery. The charger can be used in parallel with the engine
charging generator without disconnecting the charger during the operation of the
engine.
Main Features
The metal shell has good heat dissipation effect and strong anti-interference ability.
Using advanced switching power supply mode, wide AC input voltage range.
Three stage intelligent charging to maintain battery power automatically.
With short circuit and reverse connection protection.
It has charging voltage and charging current fine tune function.
It has LED which can indicate the working state of the charger.

Charging Curve
The charger is designed according to the characteristics of the lead-acid battery
used in the engine, and adopts the three-stage intelligent control mode of constant
current fast charging, current limiting and trickle floating charging. When the battery
voltage is lower than the presets value, the charging current decreases with the
increase of the battery voltage and enters the current-limiting charging stage.
Thereafter, the charging current only counteracts the self-discharge of the battery,
and maintains the battery in full state without disconnecting the charger, which has
no effect on the battery life.

Operation instruction
Charge voltage regulation:
When the charger is installed on site for voltage regulation, the battery must be
disconnected from the charger and the voltage potentiometer (VOLT) must be
adjusted at the same time as the output voltage of the charger is measured until the
appropriate value is reached.
Clockwise adjustment of the VOLT potentiometer can increase the output voltage
and reduce the output voltage by counterclockwise adjustment.
Charge current regulation:
When adjusting the current, please connect the charger output with the
accumulator group correctly, adjust when the charging voltage is not higher than
25.0V, adjust the current potentiometer (AMP) while measuring the charging current
to achieve the appropriate charging current.
Clockwise adjustment of the AMP potentiometer can increase output current and
counter clockwise adjustment to reduce output current.
Export insurance replacement:
This charger has the output anti-contact anti-insurance FUSE (10A), when the
output is connected back, the insurance will burn out, please connect the battery
correctly, replace the fuse, the charger will return to normal work. The replacement
steps are as follows:
1) Press hard on the slotted screwdriver, screw counter-clockwise and then take out
the fuse.
2) Put a new fuse into the block, press the slotted screwdriver and screw clockwise.
Note: In-proper operation or over tightening may damage the block.
Warning: When replacing the fuse, be sure to disconnect the input power
of the charger to avoid personal injury or equipment damage!
Note:
1) Because there is diode and current-limiting circuit inner the charger, it can be used
together with charging generator, and there is no need to disconnect the charger
when cranking.
2) During gen-set is running, high current will cause voltage drop in charging line, so
recommend separately connecting to battery terminal to avoid disturbance on
sampling precision.
