Power supply with double iron silicon aluminum 4 1.2MM pure copper wire and rao. 100V/210A low resistance power MOS, high power and high current input, suitable for high power LED motors Have input MOS meter protection, don't worry about input after burn out the power 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: 0.5-20A Output Power = Input Voltage * 20A, e.g. 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 power supply voltage must be above 8V. When the power supply is used for the input power supply, the input power and the output voltage of the input power supply are the first to be unloaded. Then pick up the load.(must ensure that the switching power supply has been working). When the constant current mode is used to set the voltage, the constant voltage must be higher than the input voltage.Do 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 ensure that input is lower than the output voltage. Package List: 1 x 1200W DC Converter Boost Power Supply Note: 1. Please allow 1-3 mm error due to manual measurement and 1-3g weight error make sure you don't mind before ordering. 2. Due to the lighting of the photos and the difference of monitors, the pictures may not reflect the actual color of the real item. Please make sure you don't mind before ordering, thank you!
