1.All Lumiax products PCB are designed very well, no need for labor soldering, all are welded by machine automatically, which decrease the damage risk, like cold welding\welding slag\high temperature harm to components around.
2.Most of Lumiax MOSFET are from IR, ST MOSFETs, very famous brand in the world.
3.Most of Lumiax controllers MCU are from Atmel/ST/Microchip, very famous brands in the world.
4.Lumiax uses TVS from Littelfus, No.1 brand in the world, 1200W; while others use 600W unfamous brand TVS, even some use varistors, which sensitivity are not good sometimes.
5.We have another sister company, selling the electrical components, so we have the advantages to get components with good quality and low price.
6. CE certificate approved by TUV.
