DF50AA120/160
DIODE
(THREE PHASES BRIDGE TYPE)
Power Diode Module DF50AA 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 50Amp
