Regulating transformer Rectifier

The robust rectifier which is also suitable for aggressive ambient conditions.

The basic rectifier design of the regulated transformer rectifier series is characterized by a motor-adjustable regulating transformer drive and a high-current transformer with downstream silicon diode set in 6-pulse circuit.
