                    Application:
                     
                    QS-4884CCCV-1800W is designed for lead-acid batteries, lithium batteries, solar cells or power supply boosting for electric vehicle boost and battery charging. It is very powerful.
                     
                    1. For example, the original battery of the electric vehicle is 48V, which can be boosted to 60V to supply electric vehicles, which can improve the speed and acceleration of the electric vehicle.
                    2. Charge your electric bicycle. (1: For example, if you have a 12V or 24 idle battery in your hand, you can charge the original battery after boosting this boost power supply, which is equivalent to charging a battery for an electric car. 2: Simultaneous input It can also be connected to solar cells, wind power, generators and other power boosts to charge the primary battery to increase the battery life.)
                    3. The battery voltage can be increased to make the electric car run faster, and the built-in instrument should not exceed 10V.
                    4. Solar panel boost regulator.
                     
                    Pin mode:
                     
                    IN+ input positive, IN- input negative, OUT+ output positive, OUT-output negative
                    CV voltage regulation, CC current regulation, UVP input undervoltage protection regulation

                    Package includes:

                    1 x Power Supply Module

                    Instruction:


                    Voltage regulation:
                     
                    When the power supply is unloaded, use a flat-blade screwdriver to adjust the output terminal "V-ADJ" potentiometer (marked in the figure below) to increase clockwise and counterclockwise to adjust). Because the output capacitor capacity is large, the output voltage is When the high voltage is adjusted to a low voltage, the reaction will be slower. The adjustment of the instrument is smaller.
                     
                    Current regulation:
                     
                    Adjust the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to be connected to the load such as the LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it is connected to the output, and adjust the CC A-ADJ to the current you need. When charging, be sure to use the discharged battery to adjust the battery. The more the charge, the smaller the charge current. The default output is ESC to 10A shipment. If we need to adjust the current value of the instructions or message. Do not use the short-circuit output to adjust the current, the circuit structure of the boost module can not be adjusted by short circuit.
                     
                    Enter low battery protection adjustment:
                     
                    Low battery protection mainly prevents over-discharge of the battery when the input power is the battery. The battery voltage is too low to damage the power module and the battery. The input is also the low-voltage protection when switching the power supply.
                     
                    Method 1: For example, set 12V battery low battery protection. Connect a voltage of 11V to the input terminal of the power module. Use a flat-blade screwdriver to adjust RV1 (clockwise protection voltage value is increased, counterclockwise protection voltage is turned down) until the UVLO lamp is on. At this time, the low battery protection voltage is 11V. When the voltage drops to 11V, the power module does not rise (the input voltage is equal to the output voltage). Only when the input voltage is higher than 11V, the power supply starts to resume boosting.
                     
                    Method 2: Input the battery or switch power supply. If the UVLO lamp on the board is off, adjust the RV1 potentiometer clockwise, brighten the UVLO lamp, and then turn it clockwise two turns. If the UVLO lamp is on, turn the RV1 potentiometer counterclockwise, turn off the UVLO lamp, and then turn it two turns. (Adapt to 10V-45V voltage)

                    Precautions:
                     
                    (1) The output positive and negative poles cannot be reversed and cannot be short-circuited.
                    (2) If used for electric vehicle boost drive power supply, the input voltage must be 24V or more. The electric vehicle power is less than 500W. Because the electric motor is an inductive load, the current will be large at the moment of starting and uphill. There must be sufficient power headroom.
                    (3) When using battery, switching power supply, solar panel, generator, etc. as input source, you must lower the battery protection, otherwise it will damage the battery and power supply.
                    (4) Pay attention to ventilation and heat dissipation when working for a long time, high current, high power and full load, in order to extend the service life of the power supply.
                    (5) The module can only boost the voltage and cannot supply voltage to the electrical equipment below the input voltage. For example, charge the 12V battery with a 24V battery or charge the capacitor. Powering the lED below the input voltage
                    (6) Do not work at full load for a long time. Please keep 20% margin when working continuously. Pay attention to ventilation and heat dissipation.
