The power supply module uses double sendust magnets winded with 1.2 mm copper wires ^^ 100V/210A low resistance MOS with big power and current input, suitable for big power LED, motors ^^ Support reverse input with MOS so there is no worry about wrong input wire and burn out power supply ^^ Low voltage will module and battery against damage from over-discharge when use a storage battery as input ^^ Thickened heatsink and intelligent temperature control cooling fan dissipate heat better ^^ ^^ ^^ ^^ ^^
