DIODE(THREE PHASES BRIDGE TYPE)
DF30DB40/80
Power Diode Module DF30DB is designed for three phase full wave rectification, which
has six diodes connected in a three phase bridge configuration. The mounting base of the
module is electrically isolated from semiconductor elements for simple heatsink
construction output DC current is 30Amp (Tc=83℃) Repetitive peak reverse voltage is up
to 800V.
