1200W DCDC Boost Module Adjustable Power Supply Module Constant Voltage Converter Regulator Item Type: DC Boost Module Model: SZ-BT07CCCV-A Module Type: Non Isolated Boost Module Input Voltage: DC10-60V (directly input 10-60V without jumper cap to select voltage) Input Current: Maximum 20A, if it exceeds 15A, please add a fan to dissipate heat (the input current can reach 25A when the input voltage is 12-24V after adding a fan) Quiescent Operating Current: 15mA (when 12V rises to 20V, the higher the output voltage, the higher the quiescent current will be) Output Voltage: 12-83V continuously adjustable (the default output is adjusted to 19V, if you need to adjust to other voltage values, please explain. If you have a multimeter, you can adjust it yourself) Output Current: Maximum 18A, if it exceeds 10A, please strengthen the heat dissipation (related to the input and output voltage difference, the larger the voltage difference, the smaller the output current) Constant Current Range: 0.5-18A (+/-0.3A) Input Anti Reverse Connection: Yes (150A power MOS anti reverse) Low Battery Protection: Yes (9-50V adjustable) Working Temperature: -40-+85℃ (please strengthen the heat dissipation when the ambient temperature is too high) Working Frequency: 150KHz Conversion Efficiency: 92%-97% (efficiency is related to input, output voltage, current, pressure difference. Small pressure difference, high efficiency) Input Overcurrent Protection: Yes (input over 25A, automatic protection, power supply does not boost) Short Circuit Protection: Yes (input 30A fuse), double short circuit protection, safer e. Input Reverse Connection Protection: Yes (150A power MOS tube anti-reverse. It can be reversed for a long time) Installation Method: 4pcs 3mm standoffs Wiring Method: Terminal block (please use high current pure copper wire) Module Size (L x W): Approx. 130 x 52mm / 5.1 x 2in Voltage Regulation: Use a slot screwdriver to adjust the output V-ADJ potentiometer (marked in the figure above) when the power is turned on and no load The response will be slower when adjusted to low voltage. The built in adjustment range is smaller. (The default output voltage is adjusted to 19V. If you need to adjust other voltage values, please explain or leave a message.) Current Regulation: Turn the A-ADJ potentiometer counterclockwise about 30 turns, set the output current to the minimum, connect the LED, and adjust the A-ADJ potentiometer clockwise to the current you need. For battery charging, after the battery is fully discharged, connect it to the output and adjust RV2 to the current you need. When charging, be sure e the discharged battery to adjust it, because the more battery power is left. , the smaller the charging current. (The default output ESC is 3A) Special Note: Do not adjust the current by short circuit output, and the circuit structure of the boost module cannot be adjusted by short circuit. Input Low Battery Protection Regulation: The low battery protection is mainly aimed at preventing the battery from being over discharged when the input power is a battery, and the battery voltage is too low to damage the power module and the battery. For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and adjust RV1 with a slot screwdriver (clockwise to increase the protection voltage, counterclockwise to lower the protection voltage) until the UVLO light is on. At this time, the low battery protection voltage is 10V. When the voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage).
