Description: TRU A TRU (Transformer Rectifier Unit) typically converts a three-phase 115Vac current (or 230Vac) into a direct 28Vdc current. It consists of a winded transformer, rectifying diodes and ...

They are used in power electronic applications where the power input a 50 Hz or 60 Hz sine-wave AC voltage that requires power conversion for a DC output. AC to DC converters use rectifiers to turn AC ...
