DF50BA80 SanRex - Diode Module
DF50BA80 Description
SanRex makes the DF50BA80, a diode module. It is built with six switches arranged as a three-phase bridge (6-in-1). Diode modules like this are common in rectifier front ends, DC power supplies, welders and plating equipment. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.
