Specifications: The input uses 4pcs 63V/470UF high frequency low resistance electrolytic capacitors, and the output adopts 3pcs 100V/470UF electrolytic capacitors. The 33mm ultra-high-power iron-silicon-aluminum magnetic ring is wound with three 1.2mm pure copper wires in parallel to prevent over-temperature magnetic saturation under high current conditions. When using battery power, if the battery loses power, it will not damage the power module and battery. Item Name: 1200W Booster Module Material: PCB Module: Non-isolated Boost Module Input Voltage: DC10-60V Input Current: 20A (Max). If the current is more than 15A, please add fan for heat dissipation. (when the 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 Output Current: 18A Max. Please strengthen heat dissipation if it exceeds 10A 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 Degree Celsius - 85 Degree Celsius Working Frequency: 150KHz Conversion Efficiency: 92%-97% Input Overcurrent Protection: Yes (When the input over 25A, provide automatic protection, and power supply does not boost) Short Circuit Protection: Yes. Double short circuit protection is safer to use. Input Reverse Connection Protection: Yes (150A power MOS tube anti-reverse. It can be reversed for a long time.) Installation Method: 4 x 3mm Copper Pillars Connection Method: Terminal Block (Please use high-current pure copper wire.) Output Power: Equal to Input Voltage x 20A, such as: Input 12V x 20A=240W Features: Adjustable, High Efficiency, Step-up Size: Length: 130mm/5.12", Width: 52mm/2.05", Height: 53mm/2.09" (Approx.) Notes: Due to the light and screen setting difference, the items color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Package Includes: 1 x 1200W Booster Module
