supply with double iron silicon aluminum 4 12MM pure copper wire and rao. 100V/210A low MOS, high and high current input, suitable for high LED motors Have input MOS meter protection, don't worry about input after burn out the supply With over current protection and short circuit protection Thickening of the radiator and intelligent temperature control cooling fan Conversion Efficiency: up to 95% (efficiency and input/output voltage, current, pressure related) Installation: 4pcs 3mm Screws Input Voltage: 8-60V Input Current: 20A Quiescent Current: 15mA Output Voltage: 12-80V Continuous Adjustable Output Current: 20A MAX. over 15A, please enhance heat dissipation (input and output pressure related, the greater the pressure, the smaller the output current) Constant Current Range: 05-20A Output = Input Voltage * 20A, eg. Working Temperature: -40 to 85Degrees Celsius(ambient temperature is too high, please enhance heat dissipation) Working Frequency: 150KHz Note The circuit structure of the booster module can not be adjusted by way of short circuit. The product of input supply voltage must be above 8V. When the supply is used for the input supply, the input and the output voltage of the input supply are the first to be unloaded. Then the load.(must that the switching supply has been working). When the constant current mode is used to set the voltage, the constant voltage must be higher than the input voltageDo not use the way of short circuit output current, the circuit structure of the boost module can not be adjusted in short circuit way. If the input voltage fluctuation range is lower than the set output voltage, then the output voltage is constant, it is to that input is lower than the output voltage. Package List: 1 x 1200W DC Converter Boost Supply Module Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
