This DC power supply weighs less than a laptop at just 2.8 pounds, saving more space on your workbench. And you can use it in various scenarios such as laboratory, repair, electrolysis,How to use the charging function：1.Turn on the power, press the "Battery" button (at which point the"Check" indicator light on the panel starts flashing), and adjust the voltage and current adjustment knob to the desired voltage and current value. Note: The general charging voltage is set to 1.15 times the nomina voltage of the charging battery; The charging current should be set to 0.2C (C=total battery capacity Ah). If the total battery capacity is 5000mAh, the charging current should be set to 1A2. Connect the positive and negative poles of the power host and the charging battery respectively with the output cable. After connection,the"Check" indicator light will remain on. Press the "OUTPUT" button to start charging (at this time, the "Charging" indicator light will remain on and the "Check" indicator light will be offRemarks:（2.1） lf the connection line is not properly connected (positive and negativepolarity reversed or disconnected) or if there is a problem with the battery, charging cannot start, and the "Check" indicator light will remain flashing. lt is necessary to confirm whether the connection line is correctly connected or whether the battery is damaged（2.2） lf any abnormal situations occur during the charging process, such as disconnection of the connection line, the power supply stops charging. and the "Check" indicator light starts flashing again. After troubleshooting the abnormality, press the "OUTPUT" button to continue charging.3.After the charging is completed, the "Full" indicator light lights up indicating that the battery charging has been completed.Selling Point Description:Battery positive and negative pole detection: Turn on the "BATTERY" function, and the orange light will flash. When charging the battery, if the output positive pole is connected to the battery negative pole and the output negative pole is connected to the battery positive pole, the "BATTERY" light will still flash orange, indicating a wiring error or battery damage. At this time, it is not possible to output current and voltage.[Charging Status Detection]: When the battery is charging normally, the "BATTERY" orange light is constantly on, and there is a battery level display and Ah display. The real-time display of charging power (Ah) allows you to understand the battery status.[Battery Full Stop Output]: After the battery is fully charged, the "BATTERY" light turns green and the output is disconnected. When your battery is full, our power supply will stop charging, allowing you to rest assured.[OCP Function] Overcurrent detection alarm: easily activated through the "OCP" button. Detect short circuits and overcurrent, trigger alarms and stop output to protect connected devices.Two different charging ports, USB and Type-C, facilitate fast charging of mobile phones and electronic devices that require repair.Sometimes we need to switch between different voltage or current outputs, but we often forget to unplug the previous instrument, causing it to burn out, which often occurs during maintenance. The output on/off key aims to solve this problem. By pressing the output on/off key, the required voltage and current can be adjusted without actual output power, making this DC power supply safer and more energy-efficient.Charging Function Operation Description:Turn on the "BATTERY" function, the orange light flashesWhen the battery is charging normally, the orange light "BATTERY" stays onThe "BATTERY" light flashes orange, indicating a wiring error or battery damageAfter the battery is fully charged, the "BATTERY" light turns green and the output is disconnectedFirstly, you will press the "Battery" button (the "Battery" light will start flashing yellow), and adjust the voltage and current adjustment knobs to the desired values.If the connection is incorrect (polarity heating or disconnection), or if there is a problem with the battery and charging cannot start, the "battery" light will remain ontwinkle. Confirm correct connection or check if the battery is damaged.If there is an abnormal situation such as cable disconnection during the charging process, the power supply will stop charging, and the "battery" light will start flashing again.Please solve the problem before pressing the 'OUTPUT' button to continue charging.After charging is completed, the green light on the "battery" indicates that the battery is fully charged.Charging Precautions:1. It is necessary to set the charging voltage and charging current according to the original battery manufacturer's recommendations. The charging voltage is generally 1.15 times the rated voltage of the battery, and the charging current is set to 0.2C (C=total battery capacity, unit: Ah, for example)5000mAh battery, charging current should be set to 1A. ）2. Please make sure to work in battery charging mode (press the battery button to turn on the light)3. Connect the battery correctly, with red corresponding to the positive pole and black corresponding to the negative pole. After confirming that everything is correct, press the OUTPUT button to start charging4. This product is not a professional charging device. If used for a long time, please purchase the corresponding dedicated charger5. Non professionals or untrained personnel are prohibited from using6. Please ensure that someone is on duty during the charging process and prohibit charging when leaving7. Minors are prohibited from usingIntroduction to Activating Battery Function:1> TicNe charging: Used for severely discharged batteries (such as those that have not been used for a long time) that require recharging. During the charging process, setThe charging current loss exceeds 0.1C (C=capacity in Ah), for example, for a 5Ah battery, the charging current should be set to 0.5A. After the battery is fully chargedReach the Qatar valve and switch to standard charging with 0.2c.2> Connect the positive and negative terminals of the power supply to the positive and negative terminals of the rechargeable battery using an output cable.
