Features Low voltage protection will protect module and battery against damage from over-discharge when use a storage battery as input Support reverse input protection with MOS so there is no worry about wrong input wire and burn out power supply 100V/210A low resistance MOS with big power and current input, suitable for big power LED, motors The power supply module uses double sendust magnets winded with 1.2mm copper wires Thickened heatsink and intelligent temperature control cooling fan dissipate heat better Specifications: Type: Non-isolated step-up module (BOOST) Input Voltage: DC10V to 60V Max. Input Current: 30A(input voltage 10V to 30V)                             25A(input voltage 31V to 60V) Quiescent Current: 15mA(will increase when convert 12V to 20V) Output Voltage: 12V to 90V (adjustable, default is 19V) Max. Output Current: 20A (related to the input and output voltage difference, the greater voltage difference is, the smaller output current will be. please enhance heat dissipation when current is over 15A) Constant Current Range: 0.8A to 20A(+/-0.3A) Reverse Input Protection: Yes (150A MOS) Lower Voltage Protection: Yes (V8 to 50V adjustable, self-recovery) Operating Temperature: - 40℃ to +85 ℃(if temperature is too high, please enhance heat dissipation) Frequency: 150KHz Conversion Efficiency: 92% to 97% (Efficiency is related to input/output voltage, current and voltage difference. The smaller difference is, the higher efficiency will be) Input Over-current Protection: Yes (automatically protect when input is more than 35A, and power supply voltage will not increase) Short Circuit Protection: Yes(input 30A fuse) Wiring Method: Terminals(please use large current copper wire) Max. Output Power = Input Voltage*Max Current (If input 12V, the max output power=12V*30A = 360W) Size:130 x 84 x 52mm / 5.11 x 3.3 x 2.04" Package Includes: 1 x Module Package List
