Module parameters:
 
  • Module model: SZ-BT07CCCV-A
  • Module name: 1200W boost constant current module
  • Module nature: non-isolated boost module (BOOST)
  • Input voltage: DC10-60V (direct input 10-60V without jumper cap selection voltage) (2016/5/15 update)
  • Input current: 20A (MAX) exceeds 15A, please add fan cooling (add fan input current can reach 25A when the fan input voltage is 12-24V)
  • Static working current: 15mA (12V liters 20V, the higher the output voltage, the static current will increase)
  • Output voltage: 12-83V continuously adjustable (default output is adjusted to 19V, if you have a multimeter buyer can adjust it)
  •                       12-83V fixed output (for bulk customers)
  • Output current: 18A MAX More than 10A, please strengthen the heat dissipation (related to the input and output voltage difference, the larger the differential pressure, 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 degrees (enhance heat dissipation when the ambient temperature is too high)
  • Working frequency: 150KHz
  • Conversion efficiency: 92%-97% (efficiency is related to input, output voltage, current, differential pressure. Low differential pressure)
  • Input overcurrent protection: Yes (input over 25A, automatic protection, power 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 anti-reverse. Can be reversed for a long time)
  • Installation method: 4 3mm copper columns
  • Wiring method: terminal block (please use high current pure copper wire)
  • Module size: length 130mm width 52mm height 53mm
  • Module single weight: 300 grams
 
Output power: = input voltage * 20A, such as: input 12V * 20A = 240W The maximum power when inputting 12V is 240W
                    Input voltage *20A For example: input 24V * 20A = 480W, that is: the maximum power is 480W when inputting 24V
 
Note: The maximum power is 240W when inputting 12V, the maximum power is 480W when inputting 24V, and the maximum power is 720W when inputting 36V.
 
1.The input uses four 63V/470UF high-frequency low-resistance electrolytic capacitors and outputs three 100V/470UF electrolytic capacitors.
 
2.The 33MM ultra-high-power iron-silicon-aluminum magnetic ring is wound with three 1.2MM pure copper wires to prevent over-temperature and magnetic saturation under large current conditions.
 
3.Use a piece of 116MM*58MM*14MM aluminum radiator to dissipate heat. And the heat sink has a 5015 fan (5MM*5MM*15MM) mounting hole position;
 
4.The output voltage and current of the imported power management chip are continuously adjustable.
 
 
Output voltage / output current regulation / input low battery protection regulation
 
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 above) to increase clockwise, counterclockwise to reduce), due to the large output capacitor capacity, When the output voltage is adjusted from a high voltage to a low voltage, the reaction will be slower. The adjustment of the instrument is smaller. (The default output voltage is adjusted to 19V shipment. If you 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, and adjust the "A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it is connected to the output, and the RV2 is adjusted to the current you need. When charging, you must use the battery that has been discharged. The battery is more than the remaining battery. The smaller the charging current. (The default output ESC is shipped to 3A. If you need to adjust the current value, please leave a message or leave a message.
 
Special note is:
 
Never use a short-circuit output to adjust the current. The circuit structure of the boost module cannot be adjusted by short circuit.
Input low battery protection adjustment: Low battery protection mainly prevents the battery from being over-discharged when the input power is the battery, and the battery module 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. 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 10V. The power module does not rise when the voltage drops to 10V (the input voltage is equal to the output voltage)
 
Pay attention to the following points when using the boost power supply:
 
1 The voltage of the input power supply must be above 10V.
 
2 When using the switching power supply as the input power supply, connect the input power supply and adjust the voltage first. Then go to the load. (Must ensure that the switching power supply is always working), or adjust the voltage with no load, then disconnect the switching power supply and then connect the load. Turn on the switching power supply and the power module with the switching power supply turned on. (Because the switching power supply has a climb time when it is turned on. When the voltage is lower than 10V, the chip is not working. It is easy to break down the MOS tube.
 
3 When used for constant current mode constant voltage, it must be ensured that the constant voltage must be higher than the input voltage. (For example, the input voltage of the power supply is 12V. The no-load output voltage is 15V. At this time, a 3.2V LED light is connected. This is not allowed. At least 4 LEDs connected in series are required.)
