Product description

Electrical Specifications:

AC Input Voltage: 110V/220V
DC Output Voltage: 0-100V adjustable
DC Output Current: 0-20A adjustable

Note:

The maximum output current of this product can be adjusted to 25A. For prolonged operation, it is recommended to set the current at no more than 20A to ensure stable device performance.

0utput Modes:

Lead-acid Battery Charging Mode
Lithium Battery Charging Mode
Power Supply Mode

When the charger is in operation, switching the output mode will cause the charger to automatically shut down. To resume use, manual restart is required.

Among these output modes, all three are equipped with over-temperature protection.The Lithium Battery Mode and Lead-Acid Battery Mode additionally feature reverse connection protection and short-circuit protection, while the Power Mode does not have these two protection functions.

② PCB Temperature

③ Master ControlSwitch

④ Current and Voltage Settings

Voltage and current are adjustable, with ranges of 0-100V and 0-25A respectively.Quick parameter adjustment: Press and hold the adjustment knob.Precise fine-tuning: Rotate the adjustment knob directly.Note: Do not adiust the voltage while the charger is in operation

⑤ Auto-Stop Settings

In the constant voltage (CV) mode, the charging current will decrease gradually.When the current drops to the set value, the charger will automatically shut down.

⑥ Device Operating Status

⑦ Output Mode

⑧ Device Operating Parameters

In the initial stage of charging, a high current is used to quickly replenish energy. During this period, the battery voltage rises gradually, and its real-time display value remains lower than the preset charging voltage. When the battery voltage reaches this preset value, the system will automatically switch to the constant voltage mode, and the charging current will decrease accordingly.

How to connect

Step 1: Connect to AC Power

Note: This product is available in 110V and 220V models. Before connecting to power,carefully verify that the product mode matches the input AC voltage.

Step 2:Set Parameters

This device allows parameter settings to be configured with the main power switch turned off. Therefore, please turn off the switch before setting parameters.

Step 3: Connect the battery

This product provides reverse connection and short-circuit protection only in the lead-acid mode and lithium battery mode.lf you charge the battery using the power mode, please correctly connect the positive and negative terminals of the battery.

Step 4: Turn on the main control switch

Turn on the switch, and the charger enters constant constant current mode immediately.Here, the operating voltage(lower than thepreset value)rises gradually automatically.Once reaching the preset voltage, it switches toconstant voltage mode, with the current thendecreasing gradually automatically.

FAQ

• During charging, it is necessary to overcome the battery's internal resistance and counter-electromotive force. The voltage needs to be 20%-30% higher than the nomina voltage to achleve effective charging. this is a fundamental requirement for the electrochemical charging reaction.

• Prolonged low-current charging may cause the battery temperature to rises lowly. Especially for large-capacity batteries (such as those used in electric vehicles and energy storage systems), accumulated heat can lead to issues like swelling and electrolyte leakage, and in extreme cases, even pose safety hazards.The automatic stop function can cut off power when the current drops beloweshold, fundamentally reducing the heat-related risks caused by prolonged low-current charging.

• The charger is equipped with a "delayed cooling" function. After power disconnection, the fan will keep running for a few seconds. This is a normal protective mechanism, not a malfunction, so no need to worry.

• This charger is equipped with a memory function, When disconnected from power, it automatically saves all previously configured parameters, with the exception of the switch status. Upon reconnection to power, the switch defaultsto the factory-set "Off" position. To switch it to "On", you need to access these condary menu and complete the configuration. The specific steps are as follows:

Adjust the selection box to the "Output Mode" position. Press and hold the adjustment knob to access the secondary menu. Modify the "OFF" setting displayed in the image to "ON", then return to the previous interface.

The current halves during charging due to the device's over-temperature protection mechanism. When the sensor detects a temperature of approximately 85°C, or the motherboard temperature reaches around 55°C, the charger will automatically reduce power to control the temperature. Once the temperature drops to a safe range, it will resume the original charging power.
