Module parameters: Note; the distribution copper column with fan is not suitable for the one without Module model: SZ-BT07CCCV-A1 Module name: 1200W boost constant current module Module nature: non-isolated boost module (BOOST) Input voltage: DC10-60V Input current: 20A (MAX) (when fan cooling input voltage is 12-24V, the input current can reach 25A) Static working current: 15mA (when 12V rises to 20V, the higher the output voltage, the static current will increase) Output voltage: 12-83V continuously adjustable (the default output is adjusted to 19V for shipment, if you have a multimeter, the buyer can adjust it yourself) 12-83V fixed output (for batch customers) Output current: 18A MAX, please strengthen heat dissipation if it exceeds 10A (related to the input and output pressure difference, the larger the pressure 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) Temperature-controlled fan: Yes (open the fan when it exceeds 55 degrees) Working temperature: -40~+85 degrees (please strengthen 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 to use. Input reverse connection protection: Yes (150A power MOS tube is anti-reverse. It can be reversed for a long time) Installation method: 4 3mm copper pillars Wiring mode: terminal block (please use high-current pure copper wire) Module size: length 130mm width 52mm height 53mm Module weight: 300 grams Voltage adjustment: Use a flat-blade screwdriver to adjust the output terminal V-ADJ potentiometer (marked in the figure below) clockwise to increase and counterclockwise to decrease) when the power is turned on and there is no load. Due to the large output capacitance, The response will be slower when the output voltage is adjusted from a high voltage to a low voltage. The adjustment range of the instrument is smaller. (The default output voltage is adjusted to 19V for shipment, if we need to adjust other voltage values, please explain or leave a message) Current adjustment: Adjust the A-ADJ potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the LED or current, and adjust the A-ADJ potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust to the current you need. When charging, be sure to wait until the battery is discharged and adjust (the default output is adjusted to 3A for shipment. If we need to adjust the current value or leave a message, do not adjust the current by short-circuit output. The circuit structure of the boost module cannot be adjusted by short-circuit. Input low battery protection adjustment: Low battery protection is mainly aimed at preventing battery over-discharge when the input power is a battery, and the battery voltage is too low to damage the power module and battery. For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and use a flat-blade screwdriver to adjust RV1 (clockwise protection voltage value is increased, counterclockwise protection voltage is decreased) until the UVLO light is on. At this time, the low battery protection voltage is 10V. The power module does not rise when the voltage drops to 10V (the input voltage is equal to the output voltage) The voltage of the input power supply must be above 10V.
