Product presentation:
ATEK 4000 is a smart charger based on the high-frequency PWM power supply with
an AC-DC switch and an MCU (12 bit ADC) control unit. It has a high yield with low
loss. This charger is small in size and very light.
It also has an interface with an LCD screen and a full range of protective functions. It is
the best choice for charging the batteries of your car and house as well as in an indus-
trial environment.
Features of the ATEK4000 charger:
• Automatic identification of the battery voltage (6/12 V).
• It operates in accordance with the following 4 smart charging steps:
Pre-charge
Constant current charging
Constant voltage charging
Charge maintainer/maintenance charge
• The following five charging modes are provided: 6 V, 12 Volts STD, 12 Volts AGM/
GEL 12 V STD (low temperature), 12 Volts AGM/GEL (low temperature).
• LCD screen: analogue graph, animated display with icons, which make the device
intuitive, clear and simple to use.
• Faulty battery detector, reverse polarity detector, overheat protection, short-circuit
protection.
• Charging mode selection button.
Charging specifications.
This product has 4 charging modes (pre-charge, constant intensity charging, constant
voltage charging and charge maintainer).
1-Pre-charge: Identifies the voltage of the battery before charging: if the voltage of the
battery is less than the reference voltage, the battery will be pre-charged to avoid da-
maging it. During this phase, if the battery has not attained the reference voltages (5.2
volts for 6 V batteries and 10.5 volts for the 12 V batteries), the charger will evaluate
whether the battery is faulty and the faulty battery logo will appear on the LCD screen;
get your battery tested by a professional.
2-Constant current charging: This is the main phase. The battery is charged with the
maximum current. The battery will be charged to 70% ~ 85% during this stage.
3-Constant voltage: With the constant voltage charging process, the battery voltage will
be higher and the current will gradually decrease. When the charge falls below 0.5 A,
the constant charging voltage stops and switches to the following stage. The constant
voltage charging stage is the most intense. At the end of this stage, the battery is almost
completely charged.
