DNC are suppliers of new Fanuc and GE Fanuc transistor module, for the Fanuc and GE Fanuc drive units. Whether it be DC, AC or AC Alpha, axis, servo, spindle or power supply module, DNC currently carry 3000+ Fanuc power transistor modules with the following ratings 15A, 20A, 30A, 50A, 60A, 75A, 80A, 85A, 100A, 120A, 150A, 160A, 200A, 300A, 400A over the main voltages of 500V, 550V, 600 and 1200 volts for the HV drives. There are three major types / generation of Fanuc transistor that DNC support:- darlington transistor, IGBT (isolated gate bipolar transistor), and the IPM transistor (intelligent power module). DNC do not carry the thyristors from the early dc drives, though these can be obtained on request. The Fanuc and GE Fanuc drives covered by the the transistors listed below include DC axis, AC axis and servo amp (S and C series), AC spindle drive unit (analog and digital), AC serial spindle drive unit, Alpha servo module and units, Alpha spindle modules, and Alpha power supplies as we as the Fanuc and GE Fanuc High Voltage drives.
